PART I



|ITEM 1. | BUSINESS
|------- | --------

General

BlackRock Kelso Capital Corporation (BlackRock Kelso, the Company or the Registrant, which may also be
referred to as we, us or our) provides middle-market companies with flexible financing solutions, including senior and junior secured, unsecured and subordinated debt securities and loans, and equity securities.
Our strategy is to provide capital to meet our clients current and future needs across this spectrum, creating long-term partnerships with growing middle-market companies.

We are organized as an externally-managed, non-diversified closed-end management investment company. We have elected to be regulated as a
business development company, or BDC, under the Investment Company Act of 1940, which we refer to as the 1940 Act. In addition, for tax purposes we intend to continue to qualify as a regulated investment company, or RIC, under the Internal Revenue
Code of 1986, which we refer to as the Code.

Our investment objective is to generate both current income and capital
appreciation through our debt and equity investments. We invest primarily in middle-market companies and target investments throughout the capital structure that we believe provide an attractive risk-adjusted return. The term
middle-market refers to companies with annual revenues typically between $50 million and $1 billion. Our targeted investment typically ranges between $10 million and $50 million, although the investment sizes may be more or less than the
targeted range and the size of our investments may grow with our capital availability. We generally seek to invest in companies that operate in a broad variety of industries and that generate positive cash flows.

Although most of our investments are in senior and junior secured, unsecured and subordinated loans to U.S. private and certain public
middle-market companies, we invest throughout the capital structure, which may include common and preferred equity, options and warrants, credit derivatives, high-yield bonds, distressed debt and other structured securities. We may from time to time
invest up to 30% of our assets opportunistically in other types of investments, including securities of other public companies and foreign securities.

The senior and junior secured loans in which we invest generally have stated terms of three to ten years and the subordinated debt investments we make generally have stated terms of up to ten years, but
the expected average life of such senior and junior secured loans and subordinated debt is generally between three and seven years. However, we may invest in securities of any maturity or duration. The debt that we invest in typically is not
initially rated by any rating agency, but we believe that if such investments were rated, they would be below investment grade (rated lower than Baa3 by Moodys Investors Service, lower than BBB- by Fitch Ratings or
lower than BBB- by Standard & Poors). We may invest without limit in debt of any rating, as well as debt that has not been rated by any nationally recognized statistical rating organization.

We were incorporated on April 13, 2005, commenced operations with private funding on July 25, 2005, and completed our initial
public offering on July 2, 2007. Since the commencement of our operations, the team of investment professionals of BlackRock Kelso Capital Advisors LLC (the Advisor or BlackRock Kelso Capital Advisors), including our
senior management, has evaluated more than 2,500 investment opportunities and completed 134 investments, aggregating over $2.8 billion in capital provided to middle-market companies through December 31, 2012.

During the year ended December 31, 2012, we invested approximately $317.1 million across six new and several existing portfolio

BlackRock Kelso Capital Advisors

Our investment activities are managed by the Advisor. The Advisor is responsible for sourcing potential investments, conducting research on prospective investments, analyzing investment opportunities,
structuring our investments, and monitoring our investments and portfolio companies on an ongoing basis. The Advisor is led by James R. Maher, Chairman and Chief Executive Officer of the Company and the Advisor, and Michael B. Lazar, Chief Operating
Officer of the Company and the Advisor. They are supported by the Advisors team of employees, including 14 investment professionals who have extensive experience in commercial and mezzanine lending, investment banking, accounting, corporate
law and private equity investing. Senior management as well as other key personnel of the Advisor have critical industry experience and relationships that we rely on to implement our business plan.

The Advisor has an investment committee comprised of 11 members, including Messrs. Maher and Lazar and several executives of BlackRock,
Inc. (BlackRock) and several of the principals of Kelso & Company, L.P. (the Kelso Principals). We benefit from the extensive and varied relevant experience of the BlackRock executives and the Kelso Principals
serving on the Advisors investment committee.

BlackRock is a leader in investment management, risk management and
advisory services for institutional and retail clients worldwide. At December 31, 2012, BlackRocks assets under management were $3.79 trillion.

The Kelso Principals have an average tenure of over 21 years at Kelso & Company, L.P. (Kelso). Kelso is a leading private equity firm and since 1980 has raised over $10 billion of
committed private equity capital, investing primarily in middle-market companies across a broad range of industries and through different economic and interest rate environments. Kelso as an organization does not participate in the activities of the
Advisor or advise us.

Our executive officers and directors and the employees of the Advisor and members of its investment
committee serve or may serve as investment advisors, officers, directors or principals of entities or investment funds that operate in the same or a related line of business as we do and/or investment funds managed by our affiliates. We note that
any affiliated investment vehicle currently formed or formed in the future and managed by the Advisor or its affiliates may have overlapping investment objectives with our own and, accordingly, may invest in asset classes similar to those targeted
by us. As a result, the Advisor and/or its affiliates may face conflicts in allocating investment opportunities between us and such other entities. Accordingly, we may not be given the opportunity to participate in certain investments made by
investment funds managed by advisors affiliated with the Advisor. However, the Advisor and its affiliates will endeavor to allocate investment opportunities in a fair and equitable manner and consistent with applicable allocation procedures. In any
such case, if the Advisor forms other affiliates in the future, we may co-invest on a concurrent basis with such other

affiliates, subject to compliance with applicable regulations and regulatory guidance, as well as applicable allocation procedures. In certain circumstances, negotiated co-investments may be made
only if we receive an order from the Securities and Exchange Commission (SEC) permitting us to do so.

Administration

We have
entered into an administration agreement with BlackRock Financial Management, Inc. (the Administrator) under which the Administrator provides certain administrative services to us. For providing these services, facilities and personnel,
we reimburse the Administrator for our allocable portion of overhead and other expenses incurred by the Administrator in performing its obligations under the administration agreement, including rent and our allocable portion of the cost of certain
of our officers and their respective staffs.

Market opportunity

We believe there are abundant opportunities for investments in middle-market companies with attractive risk-adjusted returns for several
reasons, including:

The current market environment may mean more favorable terms for investments in middle-market
companies. We believe the tight supply of credit due to deleveraging by banks provides a promising environment in which to originate investments in middle-market companies. We believe we are able to structure investments with lower leverage
multiples, higher current returns, greater opportunity for equity appreciation, better prepayment protection, and more meaningful financial covenants than are typically available on commensurate investments in large liquid market companies.

Middle-market companies have faced increasing difficulty in accessing the capital markets. While many middle-market
companies were able to raise funds by raising debt in the capital markets in the past, we believe this approach to financing has become more difficult, as transactions have increased in size to address investors demands for greater liquidity
in securities such as high yield bonds. In addition, we believe that many senior lenders have, in recent years, de-emphasized their service and product offerings to middle-market businesses in favor of lending to large corporate clients and managing
large, liquid capital markets transactions.

There is a large pool of uninvested private equity capital likely to seek
additional capital to support private investments. We believe there is a large pool of uninvested private equity capital available to middle-market companies. We expect that private equity firms will be active investors in middle-market
companies and that these private equity firms will seek to supplement their equity investments with senior secured and junior loans and equity co-investments from other sources, such as us.

Middle-market companies are increasingly seeking private sources for debt and equity capital. We believe that many middle-market
companies prefer to execute transactions with private capital providers such as us, rather than execute high-yield bond or equity transactions in the public markets, which may necessitate increased financial and regulatory compliance and reporting
obligations.

Consolidation among commercial banks has reduced the focus on middle-market business. We believe that
many senior lenders have de-emphasized their service and product offerings to middle-market companies in favor of lending to large corporate clients, managing capital markets transactions and providing other non-credit services to their customers.

Competitive advantages

We believe we possess the following competitive advantages over other capital providers to middle-market companies:

Demonstrated ability to deploy capital consistent with our investment policies. Since our inception, the Advisor has invested in excess of $2.8 billion across 134 portfolio companies through
December 31, 2012. We

have a portfolio yield at fair value of approximately 12.6% at December 31, 2012. In 2012, we invested approximately $317.1 million of gross assets across six new and several existing
portfolio companies.

Proven transaction sourcing strategy. Since the Advisors inception of operations, it
has sourced and reviewed more than 2,500 potential investments and has a proven process through which it has invested in excess of $2.8 billion through December 31, 2012. The Advisor identifies potential investments through its dynamic
transaction origination efforts. The origination efforts include calling on financial institutions such as investment banks, commercial banks, specialty finance companies and private equity firms; as well as on advisory firms, trade associations and
the owners and managers of middle-market companies with whom its investment professionals and investment committee members have relationships. In addition to its investment professionals, senior members of the Advisors investment committee
have relationships with a large and diverse group of financial intermediaries. We expect that our ability to leverage these relationships will continue to result in the referral of investment opportunities to us and provide us with a competitive
advantage.

Highly experienced investment team and access to BlackRock and Kelso Principals broad investing
capabilities.Our investment activities are carried out by BlackRock Kelso Capital Advisors LLC and led by James R. Maher and Michael B. Lazar with guidance from the Advisors investment committee. The investment committee is comprised of
members of BlackRock and the Kelso Principals. The Advisors investment professionals, as well as members of the investment committee, have extensive experience in fixed income, public equity and private equity investing, and possess a broad
range of transaction, financial, managerial and investment skills. Our Advisors relationship with BlackRock and the Kelso Principals augment our access to extensive expertise across asset classes.

Disciplined investment process with focus on preservation of capital. In making investment decisions, the Advisor employs a
disciplined and selective review process that focuses on, among other things, a thorough analysis of the underlying issuers business and the performance drivers of that business, as well as an assessment of the legal and economic features of
each particular investment.

Cost-effective and high quality infrastructure. We benefit from the existing
infrastructure and administrative capabilities of the Administrator. For providing these services, facilities and personnel, we reimburse the Administrator for our allocable portion of overhead and other expenses incurred by the Administrator in
performing its obligations under the administration agreement.

Operating and regulatory structure

Our investment activities are managed by the Advisor and supervised by our Board of Directors, a majority of whom are independent of the
Advisor, BlackRock, the Kelso Principals and their respective affiliates. The Advisor is registered under the Investment Advisers Act of 1940, or the Advisers Act. Under our investment management agreement (Management Agreement), we have
agreed to pay the Advisor an annual base management fee based on our total assets, as well as an incentive management fee based on our performance. The Management Agreement also provides that we will reimburse the Advisor for costs and expenses
incurred by the Advisor for office space rental, office equipment and utilities allocable to the Advisor under that agreement, as well as any costs and expenses incurred by the Advisor relating to any non-investment advisory, administrative or
operating services provided by the Advisor to us.

Also, while we may borrow funds to make investments, our ability to use
debt is limited in certain significant respects. As a BDC and a RIC for tax purposes, we are dependent on our ability to raise capital through the issuance of our common stock. RICs generally must distribute substantially all of their earnings to
stockholders as dividends in order to achieve pass-through tax treatment, which prevents us from using those earnings to support operations, which may include new investments (including investments into existing portfolio companies). Further, BDCs
must maintain an asset coverage ratio (the ratio of total assets less total liabilities other than indebtedness to total indebtedness) of not less than 200% in order to incur debt or issue senior securities, meaning generally that for every dollar
of debt incurred or senior securities issued, we must have two dollars of assets. Our existing debt arrangements also require that we maintain an asset coverage ratio of not less than 200%, among other things.

Portfolio composition

We have built an investment portfolio that includes primarily senior and junior secured, senior and junior unsecured and subordinated loans to U.S. private middle-market companies. We invest a range of
$10 million to $50 million of capital, on average, per transaction, although the investment sizes may be more or less and are expected to grow with our capital availability. Although most of our investments are in senior and junior secured, senior
and junior unsecured and subordinated loans to U.S. private and certain public middle-market companies, we invest throughout the capital structure of these companies in other securities, which may include common and preferred equity, options and
warrants, credit derivatives, high-yield bonds, distressed debt and other structured securities. We generally seek to invest in companies that operate in a broad variety of industries and that generate positive cash flows. While our focus is to
generate current income through these investments, we also seek capital appreciation.

We generally are not permitted to
invest in any private company in which any of our affiliates holds an existing investment, except to the extent permitted by the 1940 Act. We may, however, co-invest on a concurrent basis with our affiliates, subject to compliance with applicable
regulations and regulatory guidance, as well as applicable allocation procedures. We may invest, to the extent permitted by law, in the securities and instruments of other investment companies, including private funds.

At December 31, 2012, our net portfolio of 47 portfolio companies was invested 52% in senior secured loans, 18% in senior secured
notes, 16% in unsecured or subordinated debt securities, 13% in equity investments and 1% in cash and cash equivalents.

Investment selection criteria

The Advisor chooses investments and constructs our portfolio based on the investment experience of its professionals and a detailed
investment analysis for each investment opportunity. In analyzing each prospective portfolio company, the Advisor has identified several criteria it believes are important in identifying and investing in prospective portfolio companies. These
criteria provide general guidelines for the Advisors investment decisions on our behalf, although each prospective portfolio company may fail to meet one or more of these criteria. Generally, the Advisor seeks to utilize its access to
information generated by its investment professionals and investment committee members to identify investment candidates and to structure investments quickly and effectively.

Value Orientation/Positive Cash Flow. The Advisors investment philosophy places a premium on fundamental analysis from an investors perspective and has a distinct value
orientation. The Advisor focuses on companies in which it can invest at relatively low multiples of operating cash flow and that are profitable at the time of investment on an operating cash flow basis. Typically, the Advisor does not invest in
start-up companies or companies having speculative business plans.

Experienced Management. The Advisor generally
requires that portfolio companies have an experienced management team. The Advisor also generally requires portfolio companies to have in place proper incentives to induce management to succeed and to act in concert with our interests as investors,
which may include having significant equity interests.

Strong Competitive Position in Industry. The Advisor seeks
to invest in companies that have strong market positions within their respective markets or market niches and are well positioned to capitalize on growth opportunities. The Advisor seeks companies that demonstrate significant competitive advantages
versus their competitors, which it believes should help to protect their market position and profitability.

Exit
Strategy. The Advisor seeks to invest in companies that it believes will provide a steady stream of cash flow to repay loans and/or build equity value. With respect to loans and debt securities, the Advisor expects that such internally
generated cash flow, leading to the payment of interest on, and the repayment of the principal of, our investments will be a key means by which we exit these investments over time. In addition, the Advisor also seeks to invest in companies whose
business models and expected future cash flows offer attractive exit possibilities. These companies include candidates for strategic acquisition by other industry participants and companies that may repay our investments through an initial public
offering of common stock or another capital market transaction. With respect to our equity investments, the Advisor will look to exit such investments via repurchases by the portfolio company, public offerings and sales pursuant to merger and
acquisition transactions.

Liquidation Value of Assets. The prospective liquidation value of the assets, if any,
collateralizing loans in which we invest is an important factor in the Advisors credit analysis. The Advisor emphasizes both tangible assets, such as accounts receivable, inventory, equipment and real estate, and intangible assets, such as
intellectual property, customer lists, networks and databases.

Generally, the Advisor utilizes access to information
generated by its investment professionals to identify investment candidates and to structure investments quickly and effectively. Furthermore, the Advisor seeks to identify those companies exhibiting superior fundamental risk-reward profiles and
strong defensible business franchises while focusing on the relative value of the security in the companys capital structure.

Investment selection process

The Advisor selectively narrows prospective investment opportunities through a process designed to identify the most attractive opportunities. If the senior investment professionals responsible for the
transaction and the Advisors senior management determine that an investment opportunity merits pursuit, the Advisor engages in an intensive due diligence process. This process involves extensive research into the target company, its
management, its industry, its growth prospects and its ability to withstand adverse conditions.



8



---

##### Table of Contents

In conducting their due diligence, the Advisors investment professionals use publicly
available information as well as information from their extensive relationships with former and current management teams, consultants, competitors and investment bankers, among others. Though each transaction involves a somewhat different approach,
the Advisor often undertakes the following due diligence steps. Initially, the investment team involved in the transaction may meet with management to get an insiders view of the business and probe for potential weaknesses in business
prospects. They may also visit headquarters and company operations, meeting topand middle-level executives. Independently from the company, the investment team may check managements backgrounds and references. With information provided
by the company, the investment team performs a detailed review of historical financial performance and the quality of earnings. To assess both business prospects and standard practices, they may contact customers and vendors and conduct a
competitive analysis, comparing the company to its main competitors on an operating, financial, market share and valuation basis. The investment team also researches the industry for historic growth trends and future prospects utilizing industry
analysts at BlackRock, third party research, industry association literature and general news. Furthermore, they assess asset value and the ability of physical infrastructure and information systems to handle anticipated growth and investigate any
legal risks and the viability of current financial and accounting systems. Attorneys and independent accountants as well as outside advisors, as appropriate, may conduct additional due diligence on behalf of the Advisor.

After the Advisor has identified an investment opportunity and completed due diligence, the investment team involved in the transaction
prepares a written investment analysis. Senior investment professionals involved in the transaction review the analysis, and if they are in favor of making the potential investment, present it first to Messrs. Maher and Lazar and then, if approved
by Messrs. Maher and Lazar, to the Advisors investment committee for guidance. The investment committee is comprised of Messrs. Maher and Lazar, several executives of BlackRock and several of the Kelso Principals.

Investment structure

Once the Advisor determines that a prospective portfolio company is a suitable investment, it works with the management of that company,
any intermediaries and other capital providers, including senior and junior debt security investors and equity capital providers, to structure an investment.

We invest in portfolio companies primarily in the form of senior and junior secured loans and unsecured and subordinated loans. The senior and junior secured loans generally have terms of three to ten
years. We obtain security interests in the assets of our portfolio companies that serve as collateral in support of the repayment of the senior and junior secured loans. The collateral may take the form of first or second priority liens on the
assets of a portfolio company.

The Advisor structures unsecured and subordinated debt securities and loans to have relatively
high floating or fixed interest rates that provide us with current investment income. These debt securities and loans generally have terms of up to ten years. Such unsecured and subordinated debt securities and loans may have interest-only payments
in the early years, with amortization of principal deferred to the later years of the loan. Also, some of these loans will be collateralized by a subordinate lien on some or all of the assets of the company.

In some cases, our debt investments may provide for a portion of the interest payable to be payment-in-kind (PIK) interest.
To the extent interest is PIK, it is payable through the increase of the principal amount of the loan by the amount of the interest due on the then-outstanding principal amount of the loan. We are required to recognize PIK interest, a non-cash
source of income, as taxable income, increasing the amounts we are required to distribute to stockholders to qualify for the federal income tax benefits applicable to RICs.

In the case of the senior secured and junior loans, the Advisor tailors the terms of the investment to the facts and circumstances of the transaction and the prospective portfolio company, negotiating a
structure that aims to protect our rights and manage our risk while creating incentives for the portfolio company to achieve its business

##### Table of Contents

plan and improve its profitability. For example, in addition to seeking a senior position in the capital structure of our portfolio companies, the Advisor seeks to limit the downside potential of
our investments. The Advisor may accomplish this through requiring a total return on our investment (including both interest and potential equity appreciation) that compensates us for credit risk or through incorporating call protection into the
investment structure. The Advisor may also negotiate covenants in connection with our investments that protect the preservation of our capital. Such restrictions may include affirmative and negative covenants, default penalties, lien protection,
change of control provisions and board rights, including either observation or participation rights.

In general, our debt
investments include financial covenants and terms that require the portfolio company to reduce leverage over time, thereby enhancing its credit quality. These methods may include, among others: maintenance leverage covenants requiring a decreasing
ratio of debt to cash flow; maintenance cash flow covenants requiring an increasing ratio of cash flow to interest expense and possibly other cash expenses such as capital expenditures, cash taxes and mandatory principal payments; and debt
incurrence prohibitions, limiting a companys ability to relever its balance sheet. In addition, limitations on asset sales and capital expenditures prevent a company from changing the nature of its business or capitalization without our
consent.

Structurally, subordinated loans usually rank junior in priority of payment to senior debt, such as senior bank
debt, and are often unsecured. As such, other creditors may rank senior to us in the event of insolvency. However, subordinated loans rank senior to common and preferred equity in a borrowers capital structure. Due to their higher risk profile
and often less restrictive covenants as compared to senior loans, subordinated loans generally earn higher interest yields than senior secured loans. We believe that subordinated loans offer an attractive alternative investment opportunity. In many
cases investors in subordinated loans receive opportunities to invest directly in the equity securities of borrowers, and from time to time also may receive warrants to purchase equity securities.

Our debt investments may include equity features, such as warrants or options to buy a minority interest in the portfolio company.
Warrants we receive with our debt may require only a nominal cost to exercise, and thus, as a portfolio company appreciates in value, we may achieve additional investment return from this equity interest. We generally seek to structure the warrants
to provide provisions protecting our rights as a minority-interest holder, and we generally seek to structure puts or rights to sell such securities back to the company upon the occurrence of specified events.

Our equity investments may consist of preferred equity that pays dividends on a current basis or preferred equity that does not pay
current dividends. Preferred equity generally has a preference over common equity as to distributions on liquidations and dividends. In some cases, we may acquire common equity. Our equity investments frequently are not control-oriented investments,
and in many cases, we acquire equity securities as part of a group of private equity investors in which we are not the lead investor. We may also receive equity though portfolio company restructurings. Our preferred and common equity investments
typically are made in conjunction with loans to these companies.

Ongoing relationship with portfolio companies

The Advisor monitors our portfolio companies on an ongoing basis. The Advisor monitors the financial trends of each portfolio company to
determine if it is meeting its business plans and to assess the appropriate course of action for each company.

The Advisor
has several methods of evaluating and monitoring the performance and fair values of our investments, which may include the following and other methods:



| |  |  | assessment of success of the portfolio company in adhering to its business plan and compliance with covenants;
| | - |  | --------------------------------------------------------------------------------------------------------------



| |  |  | periodic and regular contact with portfolio company management and, if appropriate, the financial or strategic sponsor, to discuss financial position,
requirements and accomplishments;

Managerial assistance

As a BDC, we offer, and must provide upon request, managerial assistance to our portfolio companies. This assistance could involve, among
other things, participating in board and management meetings, consulting with and advising officers of portfolio companies and providing other organizational and financial guidance or exercising strategic or managerial influence over such companies.
We may receive fees for these services. The Advisor will provide managerial assistance on our behalf to those portfolio companies that request this assistance. Employees of the Advisor have experience providing managerial assistance to private
operating companies like our portfolio companies, and such assistance has tended to be related to board representation and to strategic and financing transactions. The Advisor generally will not receive any direct compensation from our portfolio
companies for providing managerial assistance although it may do so from time to time.

Investment rating system

The Advisor employs a grading system for our entire portfolio. The Advisor grades all loans on a scale of 1 to 4. This system is
intended to reflect the performance of the borrowers business, the collateral coverage of the loans and other factors considered relevant. Generally, the Advisor assigns only one loan grade to each portfolio company for all loan investments in
that portfolio company; however, the Advisor will assign multiple ratings when appropriate for different investments in one portfolio company. The following is a description of the conditions associated with each investment rating:

Grade 1: Investments in portfolio companies whose performance is substantially within the Advisors expectations and whose
risk factors are neutral to favorable to those at the time of the original investment.

Grade 2: Investments in
portfolio companies whose performance is below the Advisors expectations and that require closer monitoring; however, no loss of investment return (interest and/or dividends) or principal is expected.

Grade 3: Investments in portfolio companies whose performance is below the Advisors expectations and for which risk has
increased materially since origination. Some loss of investment return is expected, but no loss of principal is expected. Companies graded 3 generally will be out of compliance with debt covenants and will be unlikely to make debt repayments on
their original schedule.

Grade 4: Investments in portfolio companies whose performance is materially below the
Advisors expectations where business trends have deteriorated and risk factors have increased substantially since the original investment. Investments graded 4 are those for which some loss of principal is expected.

The Advisor monitors and, when appropriate, changes the investment ratings assigned to each
investment in our portfolio. In connection with our valuation process, the Advisor and Board of Directors review these investment ratings on a quarterly basis. Our average investment rating was 1.20 at December 31, 2012 and at December 31,
2011. The following is a distribution of the investment ratings of our portfolio companies at December 31, 2012 and December 31, 2011:

The investment rating process begins with each portfolio company or investment being initially evaluated
by the transaction team, led by a senior investment professional that is responsible for the portfolio company relationship. This evaluation generally is completed no less frequently than quarterly. At the Advisors weekly investment
professionals meeting, the transaction team presents an update on the activities of any company rated below Grade 1. Each quarter, all investment professionals attend a separate investment rating meeting. At these quarterly meetings, the
transaction team responsible for each portfolio investment reviews each portfolio company and suggests a rating for each investment for discussion among the investment professionals. At the conclusion of discussion, and subject to the approval of
the Advisors chief executive officer and chief operating officer, the Advisors chief financial officer records the internal investment ratings for review by the Board of Directors quarterly.

Investment management agreement

We have entered into a Management Agreement with the Advisor, under which the Advisor, subject to the overall supervision of the Board of Directors, manages our day-to-day operations of, and provides us
with investment advisory services. For providing these services, the Advisor receives a base management fee (the Management Fee) at an annual rate of 2.0% of our total assets, including any assets acquired with the proceeds of leverage,
payable quarterly in arrears.

The Management Agreement became effective on June 22, 2008 and its initial term expired on
June 22, 2010. Since then, our Board of Directors has approved the agreement for successive one year terms with the most recently approved term scheduled to expire on June 22, 2013, unless an additional one year term is approved by the
Board.

For the years ended December 31, 2012, 2011 and 2010, the Advisor earned $22,504,433, $19,841,258 and
$16,877,854, respectively, in base management fees under the Management Agreement.

Incentive Management Fee

The Management Agreement provides that the Advisor or its affiliates may be entitled to an incentive management fee
(the Incentive Fee) under certain circumstances. The determination of the Incentive Fee, as described in more detail below, will result in the Advisor or its affiliates receiving no Incentive Fee payments if returns to stockholders do
not meet an 8.0% annualized rate of return during the applicable fee measurement period, and will result in the Advisor or its affiliates receiving less than the full amount of the Incentive Fee percentage until returns to stockholders exceed an
approximate 13.3% annualized rate of return during such period. Annualized rate of return in this context is computed by reference to net asset value and does not take into account changes in the market price of the common stock.

##### Table of Contents

The Advisor will be entitled to receive the Incentive Fee if our performance exceeds a
hurdle rate during different measurement periods: trailing four quarters periods (which apply only to the portion of the Incentive Fee based on income) and annual periods (which apply only to the portion of the Incentive Fee based
on capital gains). The trailing four quarters periods for purposes of determining the income portion of the Incentive Fee payable for the three months ended December 31, 2012 and 2011 was determined by reference to the four
quarter periods ended on December 31, 2012 and 2011, respectively. The term annual period means the period beginning on July 1 of each calendar year and ending on June 30 of the next calendar year.

The hurdle rate for each measurement period is 2.0% multiplied by net asset values at the beginning of each calendar quarter during the
measurement period, calculated after giving effect to any distributions that occurred during the measurement period. A portion of the Incentive Fee is based on our income and a portion is based on capital gains. Each portion of the Incentive Fee is
described below.

Quarterly Incentive Fee Based on Income. For each trailing four quarters period, we pay
the Advisor an Incentive Fee based on the amount by which (A) aggregate distributions and amounts distributable out of taxable net income (excluding any capital gain and loss) during the period less the sum of, if negative, net unrealized
capital appreciation/(depreciation) and net realized capital gains/(losses) during the period, in excess of (B) the hurdle rate for the period. The amount of the excess of (A) over (B) described in this paragraph for each period is
referred to as the excess income amount.

The portion of the Incentive Fee based on income for each period will equal 50% of
the periods excess income amount, until the cumulative Incentive Fee payments for the period equal 20% of the periods income amount distributed or distributable to stockholders as described in clause (A) of the preceding paragraph.
Thereafter, the portion of the Incentive Fee based on income for the period will equal 20% of the periods remaining excess income amount.

For the years ended December 31, 2012, 2011 and 2010 the Advisor earned $16,997,054, $11,878,159 and $15,108,049 in Incentive Fees based on income, respectively.

Annual Incentive Fee Based on Capital Gains. The portion of the Incentive Fee based on capital gains is calculated and paid
on an annual basis beginning on July 1, 2007, the first day of the calendar quarter in which the Public Market Event occurred and each annual period thereafter, ending on June 30 of the next calendar year. For each annual period, we pay
the Advisor an Incentive Fee based on the amount by which (A) net realized capital gains, if any, to the extent they exceed gross unrealized capital depreciation, if any, occurring during the period exceeds (B) the amount, if any, by which
the periods hurdle rate exceeds the amount of income used in the determination of the Incentive Fee based on income for the period. The amount of the excess of (A) over (B) described in this paragraph is referred to as the excess
gain amount.

The portion of the Incentive Fee based on capital gains for each period will equal 50% of the periods
excess gain amount, until such payments equal 20% of the periods capital gain amount distributed or distributable to stockholders. Thereafter, the portion of the Incentive Fee based on capital gains for the period equals an amount such that
the portion of the Incentive Fee payments to the Advisor based on capital gains for the period equals 20% of the periods remaining excess gain amount. The result of this formula is that, if the portion of the Incentive Fee based on income for
the period exceeds the periods hurdle, then the portion of the Incentive Fee based on capital gains will be capped at 20% of the capital gain amount.

In calculating whether the portion of the Incentive Fee based on capital gains is payable with respect to any period, we account for our assets on a security-by-security basis. In addition we use the
period-to-period method pursuant to which the portion of the Incentive Fee based on capital gains for any period is based on realized capital gains for the period reduced by realized capital losses and gross unrealized capital
depreciation for the period. Based on current interpretations of Section 205(b)(3) of the Investment Advisers Act of 1940 by the SEC and its staff, the calculation of unrealized depreciation for each portfolio security over a period is based



13

##### Table of Contents

on the fair value of the security at the end of the period compared to the fair value at the beginning of the period. Incentive Fees earned in any of the periods described above are not subject
to modification or repayment based upon performance in a subsequent period.

We are required under accounting principles
generally accepted in the United States of America (GAAP) to accrue a hypothetical capital gains Incentive Fee based upon net realized capital gains and unrealized capital appreciation and depreciation on investments held at the end of
each period. The accrual of this hypothetical capital gains incentive fee assumes all unrealized capital appreciation and depreciation is realized in order to reflect a hypothetical capital gains incentive fee that would be payable at each
measurement date. If such amount is positive at the end of the period, then we record a capital gains incentive fee equal to 20% of such amount, less the amount of capital gains related incentive fees already accrued in prior periods. If the
resulting amount is negative, the accrual for GAAP in a given period may result in an additional expense. There can be no assurance that such unrealized capital appreciation will be realized in the future. However, it should be noted that a fee so
calculated and accrued would not be payable under the Investment Advisers Act of 1940 or the Management Agreement. Amounts actually paid will be consistent with the Advisers Act which specifically excludes consideration of unrealized capital
appreciation.

The capital gains fee due to the Advisor as calculated under the Management Agreement as described above, for
the years ended December 31, 2012, 2011 and 2010 was zero. In accordance with GAAP, the hypothetical incentive fee for the year ended December 31, 2012, resulted in a capital gains incentive fee of $5,494,735. The hypothetical incentive
fee based on capital gains was zero for the years ended December 31, 2011 and 2010.

Expenses

All investment professionals and staff of the Advisor, when and to the extent engaged in providing investment advisory and management
services, and the compensation and routine overhead expenses of such personnel allocable to such services, will be provided and paid for by the Advisor. We will bear all other costs and expenses of our operations and transactions, including those

$1,622,957, respectively, for such investment advisor expenses under the Management Agreement.

From time to time, the Advisor
may pay amounts owed by us to third party providers of goods or services. We will subsequently reimburse the Advisor for such amounts paid on our behalf. Reimbursements to the Advisor for the years ended December 31, 2012, 2011 and 2010 were
$3,107,677, $3,046,228 and $3,240,732, respectively.

Indemnification

The Management Agreement provides that in the absence of willful misfeasance, bad faith, gross negligence or reckless disregard of its
obligations thereunder, the Advisor is not liable to us or any of our stockholders for any act or omission by it or its employees in the supervision or management of our investment activities or for any loss sustained by us or our stockholders, and
provides for indemnification by us of its members, directors, officers, employees, agents and control persons for liabilities incurred by it in connection with their services to us, subject to certain limitations and conditions.

Board and stockholder approval of the Management Agreement

The Management Agreement became effective on June 22, 2008 and its initial term expired on June 22, 2010. Since then,
our Board of Directors has approved the agreement for successive one year terms with the most recently approved term scheduled to expire on June 22, 2013, unless an additional one year term is approved by the Board.

Duration and termination

The Management Agreement will continue in effect until June 22, 2013, and if not sooner terminated, will continue in effect for successive periods of twelve months thereafter, provided that each
continuance is specifically approved at least annually by both (1) the vote of a majority of our Board of Directors or the vote of a majority of our outstanding voting securities and (2) the vote of a majority of the Board of Directors who
are not parties to the Management Agreement or interested persons (as such term is defined in the 1940 Act) of any such party, cast in person at a meeting called for the purpose of voting on such approval. We may terminate the Management Agreement
as a whole at any time, without the payment of any penalty, upon the vote of a majority of our Board of Directors or a majority of our outstanding voting securities or by the Advisor, on 60 days written notice by either party to the other
which can be waived by the non-terminating party. The Management Agreement will terminate automatically in the event of its assignment.

##### Table of Contents

Organization of the Advisor

The Advisor is organized as a Delaware limited liability company. The Advisor is registered as an investment advisor
with the SEC under the Advisers Act. Its principal executive offices are located at 40 East 52ndStreet, New York, New York. James R. Maher and Michael B. Lazar, the managing members of the Advisor, are the control persons of the Advisor.

Administration agreement

We have entered into an administration agreement with the Administrator, a subsidiary of BlackRock, under which the Administrator provides
certain administrative services to us. In payment for these services, facilities and personnel, we reimburse the Administrator for our allocable portion of overhead and other expenses incurred by the Administrator in performing its obligations under
the administration agreement, including rent and our allocable portion of the cost of certain of our officers and their respective staffs.

For the years ended December 31, 2012, 2011 and 2010, we incurred $322,013, $968,721 and $587,469, respectively, for administrative services expenses payable to the Administrator under the
administration agreement.

License agreements

We have entered into a license agreement with BlackRock and the Advisor pursuant to which BlackRock has agreed to grant to the Advisor, and the Advisor has agreed to grant to us, a non-exclusive,
royalty-free license to use the name BlackRock. In addition, we have entered into a license agreement with Michael B. Lazar, our Chief Operating Officer, and the Advisor pursuant to which Mr. Lazar has agreed to grant to the
Advisor, and the Advisor has agreed to grant to us, a non-exclusive, royalty-free license to use the name Kelso. Mr. Lazar obtained this limited right to license the name Kelso under an agreement with Kelso.

Competition

A number of
entities compete with us to make the types of investments that we make. We compete with other BDCs, public and private funds, commercial and investment banks, CLO funds, commercial financing companies, insurance companies, high yield investors and,
to the extent they provide an alternative form of financing, private equity funds. Additionally, because competition for investment opportunities generally has increased among alternative investment vehicles, such as hedge funds, those entities have
begun to invest in areas they have not traditionally invested in, including investments in middle-market companies. As a result of these new entrants, competition for investment opportunities at middle-market companies has intensified. Many of our
existing and potential competitors are substantially larger and have considerably greater financial, technical and marketing resources than we do. For example, some competitors may have a lower cost of funds and access to funding sources that are
not available to us. In addition, some competitors may have higher risk tolerances or different risk assessments, which could allow them to consider a wider variety of investments and establish more relationships than us. Furthermore, many of our
competitors are not subject to the regulatory restrictions that the 1940 Act imposes on us as a BDC or the restrictions that the Code imposes on us as a RIC.

Leverage

We maintain a multi-currency $375 million senior secured credit
facility with a group of lenders, under which we had approximately $172 million of indebtedness outstanding at December 31, 2012. Availability under the facility, which we refer to as our Credit Facility, consists of $275 million in revolving
loan commitments and $100 million in term loan commitments. The term loan commitments have been fully drawn and may not be reborrowed once repaid. The Credit Facility has an accordion feature that allows the Company, under certain
circumstances, to increase the size of the Credit Facility by up to an additional $275 million of revolving loan



16

##### Table of Contents

commitments and $250 million of term loan commitments. The Credit Facility has a stated maturity date of December 6, 2013 and the interest rate applicable to borrowings thereunder is
generally LIBOR plus an applicable spread of either 3.00% or 3.25% for revolving loans, based on a pricing grid depending on the Companys credit rating, and LIBOR plus 3.00% for term loans. The Credit Facility contains customary affirmative
and negative covenants, including the maintenance of a minimum stockholders equity, the maintenance of a ratio of not less than 200% of total assets (less total liabilities other than indebtedness) to total indebtedness, and restrictions on
certain payments and issuance of debt. In addition, borrowings under the Credit Facility (and the incurrence of certain other permitted debt) are subject to compliance with a borrowing base that applies different advance rates to different types of
assets in the Companys portfolio. At December 31, 2012, we were in compliance with all financial and operational covenants required by the Credit Facility.

In January 2011, we closed a private placement issuance of $158 million in aggregate principal amount of five-year, senior secured notes with a fixed interest rate of 6.50% and a maturity date of
January 18, 2016 and $17 million in aggregate principal amount of seven-year, senior secured notes with a fixed interest rate of 6.60% and a maturity date of January 18, 2018 (collectively, the Senior Secured Notes). The Senior
Secured Notes were sold to certain institutional accredited investors pursuant to an exemption from registration under the Securities Act of 1933 (the Securities Act) as amended. Interest on the Senior Secured Notes is due semi-annually
on January 18 and July 18, commencing on July 18, 2011. The proceeds from the issuance of the Senior Secured Notes were used to fund new portfolio investments, reduce outstanding borrowings under the Credit Facility and for general
corporate purposes.

On February 19, 2013 we closed a private offering of $100 million in aggregate principal amount of 5.50%
unsecured convertible senior notes due 2018 (the Notes). The initial purchasers of the Notes fully exercised their overallotment option and purchased an additional $15 million in aggregate principal amount of the Notes. The closing of
the overallotment option took place on March 4, 2013. With the exercise of the overallotment option, a total of $115 million in aggregate principal amount of the Notes have been sold. Net proceeds to the Company from the offering, including the
exercise of the overallotment option, are approximately $111.3 million. The Notes were only offered to qualified institutional buyers as defined in the Securities Act pursuant to Rule 144A under the Securities Act.

The Notes are unsecured and bear interest at a rate of 5.50% per year, payable semi-annually in arrears. In certain circumstances
and during certain periods, the Notes are convertible into cash, shares of our common stock or a combination of cash and shares of our common stock, at our election, at an initial conversion rate of 86.0585 shares of common stock per $1,000
principal amount of the Notes, which is equivalent to an initial conversion price of approximately $11.62 per share of our common stock, subject to defined anti-dilution adjustments. We do not have the right to redeem the Notes prior to maturity.
The Notes mature on February 15, 2018, unless repurchased or converted in accordance with their terms prior to such date.

Staffing

Services necessary for our business are provided by individuals who are employees of the Advisor or the Administrator and
its affiliates, pursuant to the terms of the Management Agreement and the administration agreement. Each of our executive officers is an employee of the Advisor or the Administrator and its affiliates. Our executive officers are also executive
officers of the Advisor. Our day-to-day investment operations are managed by the Advisor. The Advisor currently has 16 investment professionals who focus on origination and transaction development and monitoring of our investments. We reimburse the
Advisor for costs and expenses incurred by the Advisor for office space rental, office equipment and utilities allocable to the Advisor under the Management Agreement, as well as any costs and expenses incurred by the Advisor relating to any
non-investment advisory, administrative or operating services provided by the Advisor to us. In addition, we reimburse the Administrator for our allocable portion of expenses it incurs in performing its obligations under the administration
agreement, including rent and our allocable portion of the cost of certain of our officers and their respective staffs.

Regulation

We are a BDC under the 1940 Act. The 1940 Act contains prohibitions and restrictions relating to transactions between BDCs and their affiliates (including any investment advisors or sub-advisors),
principal underwriters and affiliates of those affiliates or underwriters and requires that a majority of the directors be persons other than interested persons, as that term is defined in the 1940 Act. In addition, the 1940 Act provides
that we may not change the nature of our business so as to cease to be, or to withdraw our election as, a BDC unless that change is approved by a majority of our outstanding voting securities.

We may invest up to 100% of our assets in securities acquired directly from issuers in privately negotiated transactions. With respect to
such securities, we may, for the purpose of public resale, be deemed an underwriter as that term is defined in the Securities Act. We may purchase or otherwise receive warrants to purchase the common stock of our portfolio companies in
connection with acquisition financing or other investment. Similarly, in connection with an acquisition, we may acquire rights to require the issuers of acquired securities or their affiliates to repurchase them under certain circumstances. We also
do not intend to acquire securities issued by any investment company that exceed the limits imposed by the 1940 Act. Under these limits, except for registered money market funds we generally cannot acquire more than 3% of the voting stock of any
registered investment company, invest more than 5% of the value of our total assets in the securities of one registered investment company or invest more than 10% of the value of our total assets in the securities of registered investment companies
in the aggregate. With regard to that portion of our portfolio invested in securities issued by investment companies, it should be noted that such investments might subject our stockholders to additional expenses. None of these are fundamental
policies and they may be changed without stockholder approval.

Sarbanes-Oxley Act of 2002

The Sarbanes-Oxley Act of 2002 imposes a wide variety of regulatory requirements on publicly-held companies and their insiders. We have
adopted procedures to comply with the Sarbanes-Oxley Act and the regulations promulgated thereunder. The Sarbanes-Oxley Act requires us to review our policies and procedures to determine whether we comply with the Sarbanes-Oxley Act and such
regulations. We will continue to monitor our compliance with all regulations that are adopted under the Sarbanes-Oxley Act and will take actions necessary to ensure that we are in compliance therewith.

The NASDAQ Global Select Market corporate governance regulations

The NASDAQ Global Select Market has adopted corporate governance regulations with which listed companies must comply. We believe we are in compliance with such corporate governance listing standards. We
will continue to monitor our compliance with all future listing standards and will take actions necessary to ensure that we are in compliance therewith.

Privacy principles

We are committed to maintaining the privacy of
stockholders and to safeguarding our nonpublic personal information. The following information is provided to help you understand what personal information we collect, how we protect that information and why, in certain cases, we may share
information with select other parties.

Generally, we do not receive any nonpublic personal information relating to our
stockholders, although certain nonpublic personal information of our stockholders may become available to us. We do not disclose any nonpublic personal information about our stockholders or former stockholders to anyone, except as permitted by law
or as is necessary in order to service stockholder accounts (for example, to a transfer agent or third party administrator).

We restrict access to nonpublic personal information about our stockholders to the Advisors employees with a legitimate business
need for the information. We maintain physical, electronic and procedural safeguards designed to protect the nonpublic personal information of our stockholders.

|Item 1A. | Risk Factors
|-------- | ------------

You
should carefully consider these risk factors, together with all of the other information included in this Annual Report on Form 10-K, including our consolidated financial statements and the related notes thereto, before making a decision to purchase
our common stock. The risks set out below are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition
and/or operating results. If any of the following events occur, our business, financial condition and results of operations could be materially adversely affected. In such case, our net asset value and the trading price of our common stock could
decline, and you may lose all or part of your investment in the Company.

Risks Related to Our Business

We may be unable to achieve our investment objective if we are unable to manage our investments effectively.

Our ability to achieve our investment objective depends on our ability to manage our business, which depends, in turn, on the ability of
the Advisor to identify, invest in and monitor companies that meet our investment criteria. Accomplishing this result is largely a function of the Advisors investment process and, in conjunction with the Administrator, its ability to provide
competent, attentive and efficient services to us. Our executive officers and many of the members of the Advisors investment committee have substantial responsibilities to other clients in addition to their activities and responsibilities on
our behalf. The investment professionals dedicated to us may also be required to provide managerial assistance to our portfolio companies. These demands on their time may distract them or slow our rate of investment. Any failure to manage our
business effectively could have a material adverse effect on our business, financial condition and results of operations.

We operate in a highly competitive market for investment opportunities.

A number of entities compete with us to make the types of investments that we make. We compete with other BDCs, public and private funds,
commercial and investment banks, CLO funds, commercial financing companies, insurance companies, high yield investors, hedge funds and to the extent they provide an alternative form of financing, private equity funds. Many of our competitors are
substantially larger and have considerably greater financial, technical and marketing resources than we do. Some competitors may have a lower cost of funds and access to funding sources that are not available to us. In addition, some of our
competitors may have higher risk tolerances or different risk assessments, which could allow them to consider a wider variety of investments and establish more relationships than us. Furthermore, many of our competitors are not subject to the
regulatory restrictions that the 1940 Act imposes on us as a BDC and that the Code imposes on us as a RIC. We cannot assure you that the competitive pressures we face will not have a material adverse effect on our business, financial condition and
results of operations. Also, as a result of this competition, we may not be able to pursue attractive investment opportunities from time to time.

We are dependent upon senior management personnel of our investment advisor for our
future success, and if our investment advisor is unable to hire and retain qualified personnel or if our investment advisor loses any member of its senior management team, our ability to achieve our investment objective could be significantly
harmed.

We depend on the members of senior management of the Advisor, particularly its Chairman and Chief Executive
Officer, James R. Maher, and its Chief Operating Officer, Michael B. Lazar, as well as other key personnel for the identification, final selection, structuring, closing and monitoring of our investments. These employees of the Advisor have critical
industry experience and relationships that we rely on to implement our business plan. Our future success depends on the continued service of our Advisors senior management team. The departure of any of the members of our Advisors senior
management or a significant number of the members of its investment team could have a material adverse effect on our ability to achieve our investment objective. As a result, we may not be able to operate our business as we expect, and our ability
to compete could be harmed, which could cause our operating results to suffer. In addition, we can offer no assurance that BlackRock Kelso Capital Advisors LLC will remain our investment advisor, that BlackRock Financial Management, Inc. will remain
our administrator or that we will continue to have access to BlackRocks investment professionals or the Kelso Principals.

Our investment adviser has the right to resign on 60 days notice, and we may not be able to find a suitable replacement
within that time, resulting in a disruption in our operations that could adversely affect our business, financial condition and results of operations.

Our investment adviser has the right, under our Management Agreement, to resign at any time upon not less than 60 days written notice, whether we have found a replacement or not. If our investment
adviser resigns, we may not be able to find a new investment adviser or hire internal management with similar expertise and ability to provide the same or equivalent services on acceptable terms within 60 days, or at all. If we are unable to do so
quickly, our operations are likely to experience a disruption, our business, financial condition and results of operations as well as our ability to pay distributions are likely to be adversely affected and the market price of our shares may
decline. In addition, the coordination of our internal management and investment activities is likely to suffer if we are unable to identify and reach an agreement with a single institution or group of executives having the expertise possessed by
our investment adviser and its affiliates. Even if we are able to retain comparable management, whether internal or external, the integration of such management and their lack of familiarity with our investment objective may result in additional
costs and time delays that may adversely affect our business, financial condition and results of operations.

Capital
markets have experienced a period of disruption and instability. These market conditions have materially and adversely affected debt and equity capital markets in the United States and abroad, which had, and may in the future have, a negative impact
on our business and operations.

The global capital markets have experienced a period of disruption as evidenced by a
lack of liquidity in the debt capital markets, write-offs in the financial services sector, the re-pricing of credit risk and the failure of certain major financial institutions. Despite actions of the United States federal government and
foreign governments, these events contributed to worsening general economic conditions that have materially and adversely impacted the broader financial and credit markets and reduced the availability of debt and equity capital for the market as a
whole and financial services firms in particular. While the adverse effects of these conditions have abated to a degree, global financial markets have experienced significant volatility following the downgrade by Standard & Poors on
August 5, 2011 of the long-term credit rating of U.S. Treasury debt from AAA to AA+. During such market disruptions, we may have difficulty raising debt or equity capital especially as a result of regulatory constraints.

Market conditions may in the future make it difficult to extend the maturity of or refinance our existing indebtedness and any failure to
do so could have a material adverse effect on our business. The illiquidity of our



20

##### Table of Contents

investments may make it difficult for us to sell such investments if required. As a result, we may realize significantly less than the value at which we have recorded our investments. In
addition, significant changes in the capital markets, including the disruption and volatility, have had, and may in the future have, a negative effect on the valuations of our investments and on the potential for liquidity events involving our
investments. An inability to raise capital, and any required sale of our investments for liquidity purposes, could have a material adverse impact on our business, financial condition and results of operations.

Price declines and illiquidity in the corporate debt markets have adversely affected, and may in the future adversely affect, the
fair value of our portfolio investments, reducing our net asset value through increased net unrealized depreciation.

As a BDC, we are required to carry our investments at market value or, if no market value is ascertainable, at fair value as determined in
good faith by or under the direction of our Board of Directors. Decreases in the market values or fair values of our investments are recorded as unrealized depreciation, which reduces our net asset value. Depending on market conditions, we
could incur substantial realized losses and may suffer additional unrealized losses in future periods, which could have a material adverse impact on our business, financial condition and results of operations.

The recent downgrade of the U.S. credit rating and uncertainty about the financial stability of several countries in the European
Union (EU) could have a significant adverse effect on our business, results of operations and financial condition.

Due
to the current federal budget deficit concerns, S&P downgraded the federal governments credit rating from AAA to AA+ for the first time in history on August 5, 2011. This downgrade could lead to subsequent downgrades by S&P, as
well as to downgrades by the other two major credit rating agencies, Moodys and Fitch Ratings. These developments and the governments credit concerns in general, could cause interest rates and borrowing costs to rise, which may
negatively impact both the perception of credit risk associated with our debt portfolio and our ability to access the debt markets on favorable terms. In addition, a decreased credit rating could create broader financial turmoil and uncertainty,
which may weigh heavily on our stock price and our financial performance.

In 2010, a financial crisis emerged in Europe,
triggered by high budget deficits and rising direct and contingent sovereign debt in Greece, Ireland, Italy, Portugal and Spain, which created concerns about the ability of these EU peripheral nations to continue to service their
sovereign debt obligations. Despite assistance packages to Greece, Ireland and Portugal, the creation of a joint EU-IMF European Financial Stability Facility in May 2010, and a recently announced plan to expand financial assistance to Greece,
uncertainty over the outcome of the EU governments financial support programs and worries about sovereign finances persist. Risks and ongoing concerns about the debt crisis in Europe could have a detrimental impact on the global economic
recovery, sovereign and non-sovereign debt in these countries and the financial condition of European financial institutions. Market and economic disruptions have affected, and may continue to affect, consumer confidence levels and spending,
personal bankruptcy rates, levels of incurrence and default on consumer debt and home prices, among other factors. There can be no assurance that the market disruptions in Europe, including the increased cost of funding for certain governments and
financial institutions, will not spread, nor can there be any assurance that future assistance packages will be available or, even if provided, will be sufficient to stabilize the affected countries and markets in Europe or elsewhere. To the extent
uncertainty regarding the economic recovery continues to negatively impact consumer confidence and consumer credit factors, our business and results of operations could be significantly and adversely affected.

In addition to regulatory restrictions that restrict our ability to raise capital, our
debt arrangements contain various covenants which, if not complied with, could accelerate repayment of our debt, thereby materially and adversely affecting our liquidity, financial condition and results of operations.

The agreements governing our Credit Facility and Senior Secured Notes require us to comply with certain financial and operational
covenants. These covenants include:



| |  |  | restrictions on the level of indebtedness that we are permitted to incur in relation to the value of our assets;
| | - |  | ----------------------------------------------------------------------------------------------------------------



| |  |  | restrictions on our ability to incur liens; and
| | - |  | -----------------------------------------------



| |  |  | maintenance of a minimum level of stockholders equity.
| | - |  | -------------------------------------------------------

As of December 31, 2012, we were in compliance with all applicable covenants for our outstanding borrowings. However, our
continued compliance with these covenants depends on many factors, some of which are beyond our control. Accordingly, there are no assurances that we will continue to comply with the covenants in our debt arrangements. Failure to comply with
these covenants would result in a default under these arrangements which, if we were unable to obtain a waiver from the lenders thereunder, could result in an acceleration of repayments on our debt and thereby have a material adverse impact on our
business, financial condition and results of operations.

The disposition of our investments may result in contingent
liabilities.

Most of our investments will involve private securities. In connection with the disposition of an
investment in private securities, we may be required to make representations about the business and financial affairs of the portfolio company typical of those made in connection with the sale of a business. We may also be required to indemnify the
purchasers of such investment to the extent that any such representations turn out to be inaccurate or with respect to certain potential liabilities. These arrangements may result in contingent liabilities that ultimately yield funding obligations
that must be satisfied through our return of certain distributions previously made to us. Management does not believe contingent liabilities were material at December 31, 2012.

Substantially all of our assets are subject to security interests under our borrowings and if we default on our obligations, we may
suffer adverse consequences, including the lenders foreclosing on our assets.

As of December 31, 2012,
substantially all of our assets were pledged as collateral under our Credit Facility. If we default on our obligations, the lenders may have the right to foreclose upon and sell, or otherwise transfer, the collateral subject to their security
interests. In such event, we may be forced to sell our investments to raise funds to repay our outstanding borrowings in order to avoid foreclosure and these forced sales may be at times and at prices we would not consider advantageous. Moreover,
such deleveraging of our company could significantly impair our ability to effectively operate our business in the manner in which we have historically operated. As a result, we could be forced to curtail or cease new investment activities and lower
or eliminate the dividends that we pay to our stockholders.

In addition, if the lenders exercise their right to sell the
assets pledged under our borrowings, such sales may be completed at distressed sale prices, thereby diminishing or potentially eliminating the amount of cash available to us after repayment of the amounts outstanding.

Our Credit Facility matures in December 2013 and any inability to renew, extend or replace our Credit Facility could adversely
impact our liquidity and ability to find new investments or maintain distributions to our stockholders.

We maintain a
multi-currency $375 million senior secured credit facility with a group of lenders, under which we had approximately $172 million of indebtedness outstanding at December 31, 2012. Availability under our Credit Facility consists of $275 million
in revolving loan commitments and $100 million in term loan

##### Table of Contents

commitments. The Credit Facility has a stated maturity date of December 6, 2013. There can be no assurance that we will be able to renew, extend or replace the Credit Facility upon its
maturity on terms that are favorable to us, if at all. Our ability to renew, extend or replace the Credit Facility will be constrained by then-current economic conditions affecting the credit markets. In the event that we are not able to renew,
extend or replace the Credit Facility at the time of its maturity, this could have a material adverse effect on our liquidity and ability to fund new investments, our ability to make distributions to our stockholders and our ability to qualify as a
RIC.

Our five-year Senior Secured Notes mature in January 2016 and our seven-year Senior Secured Notes mature in
January 2018, and any inability to replace or repay our Senior Secured Notes could adversely impact our liquidity and ability to fund new investments or maintain distributions to our stockholders.

In January 2011, we closed a private placement issuance of $158 million in aggregate principal amount of five-year, senior secured
notes with a fixed interest rate of 6.50% and a maturity date of January 18, 2016 and $17 million in aggregate principal amount of seven-year senior secured notes with a fixed interest rate of 6.60% and a maturity date of January 18, 2018.
There can be no assurance that we will be able to replace the Senior Secured Notes upon their maturity on terms that are favorable to us, if at all. Our ability to replace the Senior Secured Notes will be constrained by then-current economic
conditions affecting the credit markets. In the event that we are not able to replace or repay the Senior Secured Notes at the time of their maturity, this could have a material adverse effect on our liquidity and ability to fund new investments,
our ability to make distributions to our stockholders and our ability to qualify as a RIC.

Our five-year Unsecured
Convertible Senior Notes are due in February 2018. Any inability to replace or repay our Unsecured Convertible Senior Notes could adversely impact our liquidity and ability to fund new investments or maintain distributions to our stockholders.
Conversion of the Unsecured Convertible Senior Notes to shares of the Companys common stock could result in dilution per share for existing shareholders.

On February 19, 2013 we closed a private offering of $100 million in aggregate principal amount of 5.50% unsecured convertible senior notes due 2018. The initial purchasers of the Notes fully exercised
their overallotment option and purchased an additional $15 million in aggregate principal amount of the Notes. The closing of the overallotment option took place on March 4, 2013. With the exercise of the overallotment option, a total of $115
million in aggregate principal amount of the Notes have been sold. Net proceeds to the Company from the offering, including the exercise of the overallotment option, are approximately $111.3 million. The Notes were only offered to qualified
institutional buyers as defined in the Securities Act pursuant to Rule 144A under the Securities Act.

The Notes are unsecured
and bear interest at a rate of 5.50% per year, payable semi-annually in arrears. In certain circumstances and during certain periods, the Notes are convertible into cash, shares of our common stock or a combination of cash and shares of our
common stock, at our election, at an initial conversion rate of 86.0585 shares of common stock per $1,000 principal amount of the Notes, which is equivalent to an initial conversion price of approximately $11.62 per share of our common stock,
subject to defined anti-dilution adjustments. We do not have the right to redeem the Notes prior to maturity. The Notes mature on February 15, 2018, unless repurchased or converted in accordance with their terms prior to such date.

There can be no assurance that we will be able to replace the Notes upon their maturity on terms that are favorable to us, if at all. Our
ability to replace the Notes will be constrained by then-current economic conditions affecting the credit markets. In the event that we are not able to replace or repay the Notes at the time of their maturity, this could have a material adverse
effect on our liquidity and ability to fund new investments, our ability to make distributions to our stockholders and our ability to qualify as a RIC.

If we incur additional debt, it could increase the risk of investing in our common stock.

We have indebtedness outstanding pursuant to our Credit Facility and may enter into new facilities and/or may increase the size of our existing credit facilities. We currently have outstanding $175
million of Senior

##### Table of Contents

Secured Notes. We also have outstanding $115 million of Convertible Senior Notes. Lenders under our Credit Facility, Senior Secured Notes and Convertible Senior Notes have fixed dollar claims on
our assets that are superior to the claims of our common stockholders or any preferred stockholders. We have granted a security interest in our assets in connection with our Credit Facility and Senior Secured Notes.

In the case of a liquidation event, those lenders would receive proceeds before our stockholders. In addition, borrowings, also known as
leverage, magnify the potential for gain or loss on amounts invested and, therefore, increase the risks associated with investing in our common stock. Leverage is generally considered a speculative investment technique. If the value of our assets
increases, then leveraging would cause the net asset value attributable to our common stock to increase more than it otherwise would have had we not leveraged. Conversely, if the value of our assets decreases, leveraging would cause the net asset
value attributable to our common stock to decline more than it otherwise would have had we not leveraged. Similarly, any increase in our revenue in excess of interest expense on our borrowed funds would cause our net income to increase more than it
would without the leverage. Any decrease in our revenue would cause our net income to decline more than it would have had we not borrowed funds and could negatively affect our ability to make distributions on our common stock. Our ability to service
any debt that we incur depends largely on our financial performance and is subject to prevailing economic conditions and competitive pressures.

As a BDC, we generally are required to meet a coverage ratio of total assets to total borrowings and other senior securities, which include all of our borrowings and any preferred stock we may issue in
the future, of at least 200%. If this ratio declines below 200%, we may not be able to incur additional debt and may need to sell a portion of our investments to repay some debt when it is disadvantageous to do so, and we may not be able to make
distributions.

Illustration. The following table illustrates the effect of leverage on returns from an investment in
our common stock assuming various annual returns, net of expenses. The calculations in the table below are hypothetical and actual returns may be higher or lower than those appearing below. The calculation is based on our level of borrowing at
December 31, 2012, which represented borrowings equal to 32% of our total assets. On such date, we also had $1,090 million in total assets; an average cost of funds of 4.95%; $347 million in debt outstanding; and $687 million of total net
assets. In order to compute the Corresponding Return to Common Stockholders, the Assumed Return on Portfolio (Net of Expenses Other than Interest) is multiplied by the total value of our assets at December 31, 2012 to
obtain an assumed return to us. From this amount, the interest expense calculated by multiplying the interest rate of 4.95% by the $347 million debt is subtracted to determine the return available to stockholders. The return available to
stockholders is then divided by the total value of our net assets at December 31, 2012 to determine the Corresponding Return to Common Stockholders. Actual interest payments may be different.



|                                                                     |  |        |  |        |  |       |  |      |  |

|(1) | The assumed portfolio return in the table is based on SEC regulations and is not a prediction of, and does not represent, our projected or actual performance. The table
also assumes that we will maintain a constant level of leverage. The amount of leverage that we use will vary from time to time.

Our use of borrowed funds to make investments exposes us to risks typically associated with leverage.

We borrow money and may issue additional debt securities or preferred stock to leverage our capital structure. As a result:



| |  |  | shares of our common stock are exposed to incremental risk of loss; therefore, a decrease in the value of our investments would have a greater negative
impact on the value of our common shares than if we did not use leverage;

There is a risk that we may not make distributions and consequently will be subject to
corporate-level income tax.

We intend to make distributions on a quarterly basis to our stockholders out of assets
legally available for distribution. We may not be able to achieve operating results that will allow us to make distributions at a specific level or to increase the amount of these distributions from time to time. In addition, due to the asset
coverage test applicable to us as a BDC, we may be limited in our ability to make distributions. Also, restrictions and provisions in our existing and any future debt arrangements may limit our ability to make distributions. If we do not distribute
a certain percentage of our income annually, we could fail to qualify for tax treatment as a RIC, and we would be subject to corporate-level federal income tax. We cannot assure you that you will receive distributions at a particular level or at
all.

We may have difficulty paying our required distributions if we recognize income before or without receiving cash
representing such income.

In accordance with GAAP and tax regulations, we include in income certain amounts that we
have not yet received in cash, such as PIK interest. The increases in loan balances as a result of contracted PIK arrangements are included in income for the period in which such PIK interest was received, which is often in advance of receiving cash
payment. We also may be required to include in income certain other amounts that we will not receive in cash. Any warrants that we receive in connection with our debt investments are generally valued as part of the negotiation process with the
particular portfolio company. As a result, a portion of the aggregate purchase price for the debt investments and warrants are allocated to the warrants that we receive. This will generally result in original issue discount for tax
purposes, which we must recognize as ordinary income, increasing the amounts we are required to distribute to qualify for the federal income tax benefits applicable to RICs. Because such original issue discount income would not be accompanied by
cash, we would need to obtain cash from other sources to satisfy such distribution requirements. If we are unable to obtain cash from other sources to satisfy such distribution requirements, we may fail to qualify for favorable tax treatment as a
RIC and, thus, could become subject to a corporate-level income tax on all of our income. Other features of the debt instruments that we hold may also cause such instruments to generate original issue discount, resulting in a dividend distribution
requirement in excess of current cash received. Since in certain cases we may recognize income before or without receiving cash representing such income, we may have difficulty meeting the requirement to distribute at least 90% of our net ordinary
income and realized net short-term capital gains in excess of realized net long-term capital losses, if any. If we are unable to meet these distribution requirements, we will not qualify for favorable tax treatment as a RIC or, even if such
distribution requirements are satisfied, we may be subject to tax on the amount that is undistributed. Accordingly, we may have to sell some of our assets, raise additional debt or equity capital or reduce new investment originations to meet these
distribution requirements and avoid tax.

##### Table of Contents

Because we are required to distribute substantially all of our net investment income
and net realized capital gains to our stockholders, we will continue to need additional capital to finance our growth.

We have elected to be treated for federal income tax purposes as a RIC under Subchapter M of the Code. If we can meet certain
requirements, including source of income, asset diversification and distribution requirements, and if we continue to qualify as a BDC, we will continue to qualify to be a RIC under the Code and will not have to pay corporate-level taxes on income we
distribute to our stockholders as dividends, allowing us to substantially reduce or eliminate our corporate-level tax liability. As a BDC, we are generally required to meet a coverage ratio of total assets to total senior securities, which includes
all of our borrowings and any preferred stock we may issue in the future, of at least 200%. This requirement limits the amount that we may borrow. Because we will continue to need capital to grow our investment portfolio, this limitation may prevent
us from incurring debt and require us to raise additional equity at a time when it may be disadvantageous to do so. We cannot assure you that debt and equity financing will be available to us on favorable terms, if at all, and debt financings may be
restricted by the terms of any of our outstanding borrowings. In addition, as a BDC, we are generally not permitted to issue equity securities priced below net asset value without stockholder approval. If additional funds are not available to us, we
could be forced to curtail or cease new lending and investment activities, and our net asset value and profitability could decline.

Any unrealized losses we experience on our investment portfolio may be an indication of future realized losses, which could reduce our income available for distribution.

Decreases in the market values or fair values of our investments will be recorded as unrealized depreciation. Any unrealized losses in our
investment portfolio could be an indication of a portfolio companys inability to meet its repayment obligations to us with respect to the affected investments. This could result in realized losses in the future and ultimately in reductions of
our income available for distribution in future periods.

Our investment advisor and its affiliates, officers and
employees have certain conflicts of interest.

The Advisor, its officers and employees and members of its investment
committee serve or may serve as investment advisors, officers, directors or principals of entities or investment funds that operate in the same or a related line of business as us and/or of investment funds managed by our affiliates. Accordingly,
these individuals may have obligations to investors in those entities or funds, the fulfillment of which might not be in our best interests or the best interests of our stockholders. In addition, we note that any affiliated investment vehicle
currently formed or formed in the future and managed by the Advisor or its affiliates may have overlapping investment objectives with our own and, accordingly, may invest in asset classes similar to those targeted by us. As a result, the Advisor
and/or its affiliates may face conflicts in allocating investment opportunities between us and such other entities. Although the Advisor and its affiliates will endeavor to allocate investment opportunities in a fair and equitable manner and
consistent with applicable allocation procedures, it is possible that, in the future, we may not be given the opportunity to participate in investments made by investment funds managed by the Advisor or its affiliates. In any such case, if the
Advisor forms other affiliates in the future, we may co-invest on a concurrent basis with such other affiliates, subject to compliance with applicable regulations and regulatory guidance, as well as applicable allocation procedures. In certain
circumstances, negotiated co-investments may be made only if we receive an order from the SEC permitting us to do so. There can be no assurance when any such order would be obtained or that one will be obtained at all.

Our base management fee may induce our investment advisor to incur leverage.

Our base management fee is calculated on the basis of our total assets, including assets acquired with the proceeds of leverage. This may
encourage the Advisor to use leverage to increase the aggregate amount of and the return on our investments, even when it may not be appropriate to do so, and to refrain from delevering when it would otherwise be appropriate to do so. Under certain
circumstances, the use of increased leverage may increase the likelihood of default, which would impair the value of our common stock. Given the subjective nature of the investment decisions made by our investment adviser on our behalf, we will not
be able to monitor this conflict of interest.

##### Table of Contents

Our incentive fee structure and the formula for calculating the incentive fee may
incentivize our investment advisor to pursue speculative investments.

The incentive fee payable by us to the Advisor
may create an incentive for the Advisor to pursue investments on our behalf that are riskier or more speculative than would otherwise be the case in the absence of such compensation arrangement. The incentive fee payable to the Advisor is calculated
based on a percentage of distributions on our common stock. The incentive fee payable by us to the Advisor also may induce the Advisor to invest on our behalf in instruments that have a deferred interest feature, even if such deferred payments would
not provide cash necessary to enable us to pay current distributions to our stockholders. Under these investments, we would accrue interest over the life of the investment but would not receive the cash income from the investment until the end of
the term, if at all. Our net investment income used to calculate the income portion of our incentive fee, however, will include accrued interest. Thus, a portion of this incentive fee would be based on income that we have not yet received in cash
and may never receive in cash if the portfolio company is unable to satisfy such interest payment obligation to us. The foregoing risks could be increased because the Advisor is not obligated to reimburse us for any incentive fee received even if we
subsequently incur losses or never receive in cash income that was previously accrued.

We may not replicate the success
of BlackRock or Kelso.

We are not managed by either BlackRock or Kelso. Our investment strategies differ from those of
BlackRock, the Kelso Principals or their respective affiliates. We can provide no assurance that we will replicate the historical or future performance of BlackRocks or Kelsos investments and our investment returns may be substantially
lower than the returns achieved by those firms. As a BDC, we are subject to certain investment restrictions that do not apply to BlackRock or Kelso. In addition, recent market conditions and the current stage of the economic cycle present
significant challenges to us that have not been present in the past. Accordingly, we can offer no assurance that the Advisor will be able to continue to implement our investment objective with the same degree of success as it has in the past or that
shares of our common stock will trade at or above the current level.

Substantially all of our portfolio investments are
recorded at fair value as determined in good faith by or under the direction of our Board of Directors and, as a result, there is uncertainty regarding the value of our portfolio investments.

There is not a readily available market value for substantially all of the investments in our portfolio. We value these investments
quarterly at fair value as determined in good faith under the direction of our Board of Directors using a consistently applied valuation process in accordance with a documented valuation policy that has been reviewed and approved by our Board of
Directors. Our Board of Directors utilizes the services of one or more independent valuation firms to aid in determining the fair value of these investments. Due to the inherent uncertainty and subjectivity of determining the fair value of
investments that do not have a readily available market value, the fair value of our investments may differ significantly from the values that would have been used had a readily available market value existed for such investments and may differ
materially from the amounts we realize on any dispositions of such investments. In addition, the impact of changes in the market environment and other events on the fair values of our investments that have no readily available market values may
differ from the impact of such changes on the readily available market values for our other investments. Our net asset value could be adversely affected if our determinations regarding the fair value of our investments were materially higher than
the values that we ultimately realize upon the disposal of such investments.

We may in the future determine to fund a
portion of our investments by issuing preferred stock, which would magnify the potential gains or losses and the risks of investing in us in the same manner as our borrowings.

Preferred stock, which is another form of leverage, has the same risks to our common stockholders as borrowings because the dividends on
any preferred stock we issue must be cumulative. Payment of such



27

##### Table of Contents

dividends and repayment of the liquidation preference of such preferred stock must take preference over any dividends or other payments to our common stockholders and preferred stockholders are
not subject to any of our expenses or losses, and are not entitled to participate in any income or appreciation in excess of their stated preference.

Our Board of Directors may change our investment objective, operating policies and strategies without prior notice or stockholder approval.

Our Board of Directors has the authority to modify or waive certain of our operating policies and strategies without prior notice and
without stockholder approval (except as required by the 1940 Act). However, absent stockholder approval, we may not change the nature of our business so as to cease to be, or withdraw our election as, a BDC. We cannot predict the effect any changes
to our current operating policies and strategies would have on our business, operating results or value of our common stock. Nevertheless, the effects could adversely affect our business and impact our ability to make distributions.

We may experience fluctuations in our periodic results.

We could experience fluctuations in our periodic results due to a number of factors, some of which are beyond our control, including our
ability to make investments in companies that meet our investment criteria, the interest rates payable on the debt investments we make, the default rate on such investments, the level of our expenses (including the interest rates payable on our
borrowings and the dividend rates on any preferred stock we may issue), variations in and the timing of the recognition of realized and unrealized gains or losses, the degree to which we encounter competition in our markets and general economic
conditions. As a result of these factors, results for any period should not be relied upon as being indicative of performance in future periods.

Changes in interest rates may affect our cost of capital and net investment income.

General interest rate fluctuations may have a substantial negative impact on our investments, the value of our common stock and our rate of return on invested capital. A reduction in the interest rates on
new investments relative to interest rates on current investments could also have an adverse impact on our net investment income. An increase in interest rates could decrease the value of any investments we hold which earn fixed interest rates,
including subordinated loans, senior and junior secured and unsecured debt securities and loans and high-yield bonds, and also could increase our interest expense, thereby decreasing our net investment income. Also, an increase in interest rates
available to investors could make investment in our common stock less attractive if we are not able to increase our dividend rate, which could reduce the value of our common stock.

The effect of global climate change may impact the operations of our portfolio companies.

There may be evidence of global climate change. Climate change creates physical and financial risk and some of our portfolio companies may
be adversely affected by climate change. For example, the needs of customers of energy companies vary with weather conditions, primarily temperature and humidity. To the extent weather conditions are affected by climate change, energy use could
increase or decrease depending on the duration and magnitude of any changes. Increases in the cost of energy could adversely affect the cost of operations of our portfolio companies if the use of energy products or services is material to their
business. A decrease in energy use due to weather changes may affect some of our portfolio companies financial condition, through decreased revenues. Extreme weather conditions in general require more system backup, adding to costs, and can
contribute to increased system stresses, including service interruptions.

Risks Related to Our Investments

Our investments are risky and highly speculative, and we could lose all or part of our investment.

Investing in private middle-market companies involves a high degree of risk and our financial results may be affected adversely if one or
more of our significant portfolio investments defaults on its loans or fails to perform as we expect. We invest primarily in middle-market companies in the form of senior and junior secured

and unsecured debt securities and loans, each of which may include an equity component, and by making direct preferred, common and other equity investments in such companies.

Investing in private middle-market companies involves a number of significant risks, including these companies:



| |  |  | may have limited financial resources and may be unable to meet their obligations under their debt securities that we hold, which may be accompanied by
a deterioration in the value of any collateral and a reduction in the likelihood of us realizing any guarantees we may have obtained in connection with our investment;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | typically have shorter operating histories, narrower product lines and smaller market shares than larger businesses, which tend to render them more
vulnerable to competitors actions and market conditions, as well as general economic downturns;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | are more likely to depend on the management talents and efforts of a small group of persons; therefore, the death, disability, resignation or
termination of one or more of these persons could have a material adverse impact on our portfolio company and, in turn, on us;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | generally have less predictable operating results, may from time to time be parties to litigation, may be engaged in rapidly changing businesses with
products subject to a substantial risk of obsolescence, and may require substantial additional capital to support their operations, finance expansion or maintain their competitive position;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | may have difficulty accessing the capital markets to meet future capital needs, which may limit their ability to grow or to repay their outstanding
indebtedness upon maturity; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our executive officers, directors and the Advisor may, in the ordinary course of business, be named as defendants in litigation arising from our
investments in the portfolio companies.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In addition, in the course of providing significant managerial
assistance to certain of our portfolio companies, certain of our officers and directors may serve as directors on the boards of such companies. To the extent that litigation arises out of our investments in these companies, our officers and
directors may be named as defendants in such litigation, which could result in an expenditure of funds (through our indemnification of such officers and directors) and the diversion of management time and resources.

From time to time, we and the Advisor may be a party to certain legal proceedings incidental to the normal course of our business,
including the enforcement of our rights under contracts with our portfolio companies. While we cannot predict the outcome of these legal proceedings with certainty, we do not expect that these proceedings will have a material effect on our
consolidated financial statements. We have been named as a defendant, together with the Advisor and certain other defendants, in two wrongful death and personal injury actions filed in West Virginia at the facilities of one of our portfolio
companies. We and the Advisor have filed motions to dismiss both cases. The litigations are in the early stages and it is not possible to predict with a reasonable degree of certainty the likelihood of an unfavorable outcome or the range of a
potential loss, if any.

An investment strategy focused primarily on privately held companies presents certain
challenges, including the lack of available information about these companies.

We invest primarily in privately held
companies. Generally, little public information exists about these companies. We must therefore rely on the ability of our investment adviser to obtain adequate information to evaluate the potential risks of investing in these companies. These
companies and their financial information generally are not subject to the Sarbanes-Oxley Act of 2002 and other rules that govern public companies. If we are unable to uncover all material information about these companies, we may not make a fully
informed investment decision, and we may lose money on our investments. These factors could affect our investment returns.

##### Table of Contents

Our investments in lower credit quality obligations are risky and highly speculative,
and we could lose all or part of our investment.

Most of our debt investments are likely to be in lower grade
obligations. The lower grade investments in which we invest may be rated below investment grade by one or more nationally-recognized statistical rating agencies at the time of investment or may be unrated but determined by the Advisor to be of
comparable quality. Debt securities rated below investment grade are commonly referred to as junk bonds and are considered speculative with respect to the issuers capacity to pay interest and repay principal. The debt that we
invest in typically is not initially rated by any rating agency, but we believe that if such investments were rated, they would be below investment grade (rated lower than Baa3 by Moodys Investors Service, lower than
BBB- by Fitch Ratings or lower than BBB- by Standard & Poors). We may invest without limit in debt of any rating, as well as debt that has not been rated by any nationally recognized statistical rating
organization.

Investment in lower grade investments involves a substantial risk of loss. Lower grade securities or comparable
unrated securities are considered predominantly speculative with respect to the issuers ability to pay interest and principal and are susceptible to default or decline in market value due to adverse economic and business developments. The
market values for lower grade debt tend to be very volatile and are less liquid than investment grade securities. For these reasons, your investment in our company is subject to the following specific risks: increased price sensitivity to a
deteriorating economic environment; greater risk of loss due to default or declining credit quality; adverse company specific events are more likely to render the issuer unable to make interest and/or principal payments; and if a negative perception
of the lower grade debt market develops, the price and liquidity of lower grade securities may be depressed. This negative perception could last for a significant period of time.

Any investments in distressed debt obligations may not produce income and may require us to bear large expenses in order to protect
and recover our investment.

At times, distressed debt obligations may not produce income and may require us to bear
certain extraordinary expenses (including legal, accounting, valuation and transaction expenses) in order to protect and recover our investment. Therefore, to the extent we invest in distressed debt, our ability to achieve current income for our
stockholders may be diminished. We also will be subject to significant uncertainty as to when and in what manner and for what value the distressed debt we invest in will eventually be satisfied (e.g., through liquidation of the obligors
assets, an exchange offer or plan of reorganization involving the distressed debt securities or a payment of some amount in satisfaction of the obligation). In addition, even if an exchange offer is made or plan of reorganization is adopted with
respect to distressed debt we hold, there can be no assurance that the securities or other assets received by us in connection with such exchange offer or plan of reorganization will not have a lower value or income potential than may have been
anticipated when the investment was made. Moreover, any securities received by us upon completion of an exchange offer or plan of reorganization may be restricted as to resale. As a result of our participation in negotiations with respect to any
exchange offer or plan of reorganization with respect to an issuer of distressed debt, we may be restricted from disposing of such securities.

If we invest in preferred stock, we may incur additional risks.

To
the extent we invest in preferred securities, we may incur particular risks, including:



| |  |  | Preferred securities may include provisions that permit the issuer, at its discretion, to defer distributions for a stated period without any adverse
consequences to the issuer. If we own a preferred security that is deferring its distributions, we may be required to report income for tax purposes before we receive such distributions. Preferred securities are subordinated to bonds and other debt
instruments in a companys capital structure in terms of priority to corporate income and liquidation payments, and therefore will be subject to greater credit risk than more senior debt instruments; and

| |  |  | Generally, preferred security holders have no voting rights with respect to the issuing company unless preferred dividends have been in arrears for a
specified number of periods, at which time the preferred security holders may elect a number of directors to the issuers board. Generally, once all the arrearages have been paid, the preferred security holders no longer have voting rights.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Our equity investments may decline in value.

The equity securities in which we invest may not appreciate or may decline in value. We may thus not be able to realize gains from our
equity securities, and any gains that we do realize on the disposition of any equity securities may not be sufficient to offset any other losses we experience. As a result, the equity securities in which we invest may decline in value, which may
negatively impact our ability to pay distributions and cause you to lose all or part of your investment.

We may expose
ourselves to risks if we engage in hedging transactions.

We may enter into hedging transactions, which could expose us
to risks associated with such transactions. We may utilize instruments such as forward contracts and interest rate swaps, caps, collars and floors to seek to hedge against fluctuations in the relative values of our portfolio positions and amounts
due under our debt arrangements from changes in market interest rates. Use of these hedging instruments may include counterparty credit risk. Utilizing such hedging instruments does not eliminate the possibility of fluctuations in the values of such
positions and amounts due under our debt arrangements or prevent losses if the values of such positions decline. However, such hedging can establish other positions designed to gain from those same developments, thereby offsetting the decline in the
value of such portfolio positions. Such hedging transactions may also limit the opportunity for gain if the values of the underlying portfolio positions should increase. Moreover, it may not be possible to hedge against an interest rate fluctuation
that is so generally anticipated that we are not able to enter into a hedging transaction at an acceptable price.

The success
of our hedging transactions will depend on our ability to correctly predict movements and interest rates. Therefore, while we may enter into such transactions to seek to reduce interest rate risks, unanticipated changes in interest rates may result
in poorer overall investment performance than if we had not engaged in any such hedging transactions. In addition, the degree of correlation between price movements of the instruments used in a hedging strategy and price movements in the portfolio
positions being hedged may vary. Moreover, for a variety of reasons, we may not seek to establish a perfect correlation between such hedging instruments and the portfolio holdings or debt arrangements being hedged. Any such imperfect correlation may
prevent us from achieving the intended hedge and expose us to risk of loss. See also Changes in interest rates may affect our cost of capital and net investment income.

Economic recessions or downturns could impair our portfolio companies and harm our operating results.

Many of our portfolio companies may be susceptible to economic slowdowns or recessions and may be unable to repay our loans during these
periods. Therefore, our non-performing assets may increase and the value of our portfolio may decrease during these periods as we are required to record the values of our investments. Adverse economic conditions also may decrease the value of
collateral securing some of our loans and the value of our equity investments. Economic slowdowns or recessions could lead to financial losses in our portfolio and a decrease in revenues, net income and assets. Unfavorable economic conditions also
could increase our funding costs, limit our access to the capital markets or result in a decision by lenders not to extend credit to us. These events could prevent us from increasing investments and harm our operating results.

Our portfolio companies may incur debt that ranks equally with, or senior to, our investments in such companies.

Our portfolio companies usually will have, or may be permitted to incur, other debt that ranks equally with, or senior
to, debt securities in which we invest. By their terms, such debt instruments may provide that the



31



---

##### Table of Contents

holders are entitled to receive payment of interest or principal on or before the dates on which we are entitled to receive payments. Also, in the event of insolvency, liquidation, dissolution,
reorganization or bankruptcy of a portfolio company, holders of debt instruments ranking senior to our investment in that portfolio company would typically be entitled to receive payment in full before we receive any distribution in respect of our
investment. After repaying such senior creditors, the portfolio company may not have any remaining assets to use for repaying its obligations to us. In the case of debt ranking equally with debt securities in which we invest, we would have to share
on an equal basis any distributions with other creditors holding such debt in the event of an insolvency, liquidation, dissolution, reorganization or bankruptcy of the relevant portfolio company. In addition, we may not be in a position to control
any portfolio company by investing in its debt securities. As a result, we are subject to the risk that a portfolio company in which we invest may make business decisions with which we disagree, and the management of such company, as representatives
of the holders of its common equity, may take risks or otherwise act in ways that do not serve our interests as debt investors.

Because we generally do not hold controlling equity interests in our portfolio companies, we may not be in a position to exercise
control over our portfolio companies or to prevent decisions by management of our portfolio companies that could decrease the value of our investments.

We generally do not hold controlling equity positions in our portfolio companies. As a result, we are subject to the risk that a portfolio company may make business decisions with which we disagree, and
that the management and/or stockholders of a portfolio company may take risks or otherwise act in ways that are adverse to our interests. Due to the lack of liquidity of the debt and equity investments that we typically hold in our portfolio
companies, we may not be able to dispose of our investments in the event we disagree with the actions of a portfolio company and may therefore suffer a decrease in the value of our investments.

Concentration of our assets in an issuer, industry or sector may present more risks than if we were more broadly diversified over
numerous issuers, industries and sectors of the economy.

We are classified as a non-diversified investment company
within the meaning of the 1940 Act, which means that we are not limited by the 1940 Act with respect to the proportion of our assets that we may invest in securities of a single issuer. To the extent that we assume large positions in the securities
of a small number of issuers, our net asset value may fluctuate to a greater extent than that of a diversified investment company as a result of changes in the financial condition or the markets assessment of the issuer. We may also be more
susceptible to any single economic or regulatory occurrence than a diversified investment company.

In addition, we may, from
time to time, invest a substantial portion of our assets in the securities of issuers in any single industry or sector of the economy or in only a few issuers. We cannot predict the industries or sectors in which our investment strategy may cause us
to concentrate and cannot predict the level of our diversification among issuers to ensure that we satisfy diversification requirements for qualification as a RIC for U.S. federal income tax purposes. A downturn in an industry or sector in which we
are concentrated would have a larger impact on us than on a company that does not concentrate in that particular industry or sector. Furthermore, the Advisor has not made and does not intend to make any determination as to the allocation of assets
among different classes of securities. At any point in time we may be highly concentrated in a single type of asset, such as junior unsecured loans or distressed debt. Consequently, events which affect a particular asset class disproportionately
could have an equally disproportionate effect on us.

Our failure to make follow-on investments in our portfolio
companies could impair the value of our portfolio.

Following an initial investment in a portfolio company, we may make
additional investments in that portfolio company as follow-on investments in order to: (i) increase or maintain in whole or in part our equity ownership percentage; (ii) exercise warrants, options or convertible securities that
were acquired in the original or any subsequent financing; or (iii) attempt to preserve or enhance the value of our investments. We may elect



32



---

##### Table of Contents

not to make follow-on investments or otherwise lack sufficient funds to make those investments. We will have the discretion to make any follow-on investments, subject to the availability of
capital resources. The failure to make follow-on investments may, in some circumstances, jeopardize the continued viability of a portfolio company and our initial investment, or may result in a missed opportunity for us to maintain or increase our
participation in a successful operation. Even if we have sufficient capital to make a desired follow-on investment, we may elect not to make a follow-on investment because we may not want to increase our concentration of risk, either because we
prefer other opportunities or because we are subject to BDC requirements that would prevent such follow-on investments or the desire to maintain our RIC status.

Our investments in foreign securities may involve significant risks in addition to the risks inherent in U.S. investments.

Our investment strategy contemplates that a portion of our investments may be in securities of foreign companies. Investing in foreign
companies may expose us to additional risks not typically associated with investing in U.S. companies. These risks include changes in exchange control regulations, political and social instability, expropriation, imposition of foreign taxes
(potentially at confiscatory levels), less liquid markets and less available information than is generally the case in the U.S., higher transaction costs, less government supervision of exchanges, brokers and issuers, less developed bankruptcy laws,
difficulty in enforcing contractual obligations, lack of uniform accounting and auditing standards and greater price volatility.

Although most of our investments are denominated in U.S. dollars, our investments that are denominated in a foreign currency are subject to the risk that the value of a particular currency may change in
relation to one or more other currencies. Among the factors that may affect currency values are trade balances, the level of short-term interest rates, differences in relative values of similar assets in different currencies, long-term opportunities
for investment and capital appreciation, and political developments. We may employ hedging techniques to minimize these risks, but we can offer no assurance that we will, in fact, hedge currency risk or, that if we do, such strategies will be
effective.

Our investments in the healthcare sector face considerable uncertainties including substantial regulatory
challenges.

Our investments in the healthcare sector are subject to substantial risks. The laws and rules governing
the business of healthcare companies and interpretations of those laws and rules are subject to frequent change. Broad latitude is given to the agencies administering those regulations. Existing or future laws and rules could force our portfolio
companies engaged in healthcare to change how they do business, restrict revenue, increase costs, change reserve levels, change business practices and increase liability in federal and state courts. Healthcare companies often must obtain and
maintain regulatory approvals to market many of their products, change prices for certain regulated products and to consummate some of their acquisitions and divestitures.

Delays in obtaining or failure to obtain or maintain these approvals could reduce revenue or increase costs. Policy changes on the local, state and federal level, such as the expansion of the
governments role in the health care arena and alternative assessments and tax increases specific to the healthcare industry or healthcare products as part of federal health care reform initiatives, could fundamentally change the dynamics of
the healthcare industry.

Risks Related to Our Operations as a BDC

Our ability to enter into transactions with our affiliates is restricted.

We are prohibited under the 1940 Act from knowingly participating in certain transactions with certain of our affiliates without the prior
approval of our independent directors and, in some cases, of the SEC. Any person that owns, directly or indirectly, 5% or more of our outstanding voting securities will be our affiliate for purposes of the 1940 Act and we are generally prohibited
from buying or selling any security (other than our securities)



33



---

##### Table of Contents

from or to such affiliate, absent the prior approval of our independent directors. The 1940 Act also prohibits certain joint transactions with certain of our affiliates, which could
include investments in the same portfolio company (whether at the same or different times), without prior approval of our independent directors and, in some cases, of the SEC. We are prohibited from buying or selling any security from or to any
person who owns more than 25% of our voting securities or certain of that persons affiliates, or entering into prohibited joint transactions with such persons, absent the prior approval of the SEC through an exemptive order (other than in
certain limited situations pursuant to current regulatory guidance). The analysis of whether a particular transaction constitutes a joint transaction requires a review of the relevant facts and circumstances then existing. Similar restrictions limit
our ability to transact business with our officers or directors or their affiliates.

We have applied for an exemptive order
from the SEC that would permit us and certain of our affiliates, including investment funds managed by our affiliates, to co-invest. Any such order will be subject to certain terms and conditions and there can be no assurance that such order will be
granted by the SEC. Accordingly, we cannot assure you that we or our affiliates, including investment funds managed by our affiliates, will be permitted to co-invest, other than in the limited circumstances currently permitted by regulatory guidance
or in the absence of a joint transaction.

Regulations governing our operation as a BDC affect our ability to, and the
way in which we, raise additional capital.

Our business requires a substantial amount of capital. We may acquire
additional capital from the issuance of senior securities or other indebtedness, the issuance of additional shares of our common stock or from securitization transactions. However, we may not be able to raise additional capital in the future on
favorable terms or at all. We may issue debt securities or preferred securities, which we refer to collectively as senior securities, and we may borrow money from banks or other financial institutions, up to the maximum amount permitted
by the 1940 Act. The 1940 Act permits us to issue senior securities or incur indebtedness only in amounts such that our asset coverage, as defined in the 1940 Act, equals at least 200% after such issuance or incurrence. Our ability to pay dividends
or issue additional senior securities would be restricted if our asset coverage ratio were not at least 200%. If the value of our assets declines, we may be unable to satisfy this test. If that happens, we may be required to liquidate a portion of
our investments and repay a portion of our indebtedness at a time when such sales may be disadvantageous.



| |  |  | Senior Securities. As a result of issuing senior securities, we would also be exposed to typical risks associated with leverage, including an
increased risk of loss. If we issue preferred securities they would rank senior to common stock in our capital structure, preferred stockholders would have separate voting rights and may have rights, preferences or privileges more
favorable than those of our common stockholders. Furthermore, the issuance of preferred securities could have the effect of delaying, deferring or preventing a transaction or a change of control that might involve a premium price for our common
stockholders or otherwise be in the best interests of our common stockholders.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Additional Common Stock. Our Board of Directors may decide to issue common stock to finance our operations rather than issuing debt or other
senior securities. As a BDC, we are generally not able to issue our common stock at a price below net asset value, or issue securities convertible into common stock, without first obtaining the required approvals from our stockholders and our
independent directors. We may also make rights offerings to our stockholders. If we raise additional capital by issuing more common stock or senior securities convertible into, or exchangeable for, our common stock, the percentage ownership of our
common stockholders at that time would decrease, and our common stockholders may experience dilution.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Securitization. In addition to issuing securities to raise capital as described above, we anticipate that in the future we may securitize our
loans to generate cash for funding new investments. To securitize loans, we may create a wholly-owned subsidiary, contribute a pool of loans to the subsidiary and have the subsidiary issue primarily investment grade debt securities to purchasers who
we would expect
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| | would be willing to accept a substantially lower interest rate than the loans earn. We would retain all or a portion of the equity in the securitized pool of loans. Our retained equity would be
exposed to any losses on the portfolio of loans before any of the debt securities would be exposed to such losses. An inability to successfully securitize our loan portfolio could limit our ability to grow our business and fully execute our business
strategy and adversely affect our earnings, if any. Moreover, the successful securitization of our loan portfolio might expose us to losses as the residual loans in which we do not sell interests will tend to be those that are riskier and more apt
to generate losses.
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Stockholders will likely incur dilution if we sell or otherwise issue shares of
our common stock at prices below the then current net asset value per share of our common stock.

We obtained approval
at our 2012 Annual Meeting of Stockholders to allow us the flexibility, with the approval of our Board of Directors, to sell or otherwise issue shares of our common stock at a price below its then current net asset value per share during the twelve
month period following stockholders approval at the 2012 Annual Meeting, subject to the policy of our Board of Directors that the Company shall not sell or otherwise issue more than 25% of the Companys then outstanding shares of common stock
(immediately prior to such sale or issuance) at a price below its then current net asset value per share. Since we obtained this approval from stockholders, we may issue shares of our common stock at a price below its then current net asset value
per share, subject to the foregoing conditions and the determination by our Board of Directors that such issuance and sale is in our and our stockholders best interests.

In addition, we may also issue shares in certain limited circumstances under our dividend reinvestment plan and under interpretive advice issued by the Internal Revenue Service. Any sale or other issuance
of shares of our common stock at a price below net asset value per share would result in an immediate dilution to the net asset value per share. This dilution would occur as a result of a proportionately greater decrease in a stockholders
interest in our earnings and assets and voting interest in us than the increase in our assets resulting from such issuance. Because the number of shares of common stock that could be so issued and the timing of any issuance is not currently known,
the actual dilutive effect cannot be predicted. We caution you that such effects may be material, and we undertake to describe material risks and dilutive effects of any offering that we make at a price below our then current net asset value in the
future in a prospectus supplement issued in connection with any such offering. We cannot predict whether shares of our common stock will trade above, at or below our net asset value.

Changes in the laws or regulations governing our business or the businesses of our portfolio companies and any failure by us or our
portfolio companies to comply with these laws or regulations could negatively affect the profitability of our operations or of our portfolio companies.

We are subject to changing rules and regulations of federal and state governments, as well as the stock exchange on which our common stock is listed. These entities, including the Public Company
Accounting Oversight Board, the SEC and The NASDAQ Global Select Market, have issued a significant number of new and increasingly complex requirements and regulations over the course of the last several years and continue to develop additional
regulations. In particular, changes in the laws or regulations or the interpretations of the laws and regulations that govern BDCs, RICs or non-depository commercial lenders could significantly affect our operations and our cost of doing business.
We are subject to federal, state and local laws and regulations and are subject to judicial and administrative decisions that affect our operations, including our loan originations, maximum interest rates, fees and other charges, disclosures to
portfolio companies, the terms of secured transactions, collection and foreclosure procedures and other trade practices. If these laws, regulations or decisions change, or if we expand our business into jurisdictions that have adopted more stringent
requirements than those in which we currently conduct business, we may have to incur significant expenses in order to comply, or we might have to restrict our operations. In addition, if we do not comply with applicable laws, regulations and
decisions, we may lose licenses needed for the conduct of our business and be subject to civil fines and

##### Table of Contents

criminal penalties, any of which could have a material adverse effect upon our business, financial condition and results of operations.

The impact of recent financial reform legislation on us is uncertain.

In light of current conditions in the U.S. and global financial markets and the U.S. and global economy, legislators, the presidential
administration and regulators have increased their focus on the regulation of the financial services industry. The Dodd-Frank Wall Street Reform and Consumer Protection Act became effective on July 21, 2010; although many provisions of the
Dodd-Frank Reform Act have delayed effectiveness or will not become effective until the relevant federal agencies issue new rules to implement the Dodd-Frank Reform Act. Nevertheless, the Dodd-Frank Reform Act may have a material adverse impact on
the financial services industry as a whole and on our business, financial condition and results of operations. Accordingly, we cannot predict the effect the Dodd-Frank Reform Act or implementing its regulations will have on our business, financial
condition and results of operations.

Any failure on our part to maintain our status as a BDC would reduce our operating
flexibility.

The 1940 Act imposes numerous constraints on the operations of BDCs. Any failure to comply with the
requirements imposed on BDCs by the 1940 Act could cause the SEC to bring an enforcement action against us and/or expose us to claims of private litigants. In addition, upon approval of a majority of our stockholders, we may elect to withdraw our
status as a BDC. If we decide to withdraw our election, or if we otherwise fail to qualify, or maintain our qualification, as a BDC, we may be subject to the substantially greater regulation under the 1940 Act as a closed-end investment
company. Compliance with such regulations would significantly decrease our operating flexibility, and could significantly increase our costs of doing business.

If we do not invest a sufficient portion of our assets in qualifying assets, we could fail to qualify as a BDC or be precluded from investing according to our current business strategy.

As a BDC, we may not acquire any assets other than qualifying assets unless, at the time of and after
giving effect to such acquisition, at least 70% of our total assets are qualifying assets. We believe that most of the investments that we may acquire in the future will constitute qualifying assets. However, we may be precluded from investing in
what we believe are attractive investments if such investments are not qualifying assets for purposes of the 1940 Act. If we do not invest a sufficient portion of our assets in qualifying assets, we could be found to be in violation of the 1940 Act
provisions applicable to BDCs, which would have a material adverse effect on our business, financial condition and results of operations. Similarly, these rules could prevent us from making follow-on investments in existing portfolio companies
(which could result in the dilution of our position) or could require us to dispose of investments at inappropriate times in order to come into compliance with the 1940 Act. Because most of our investments will be in private companies, and therefore
will be relatively illiquid, any such dispositions could be made at disadvantageous prices and could result in substantial losses.

Loss of status as a RIC would reduce our net asset value and distributable income.

We currently qualify as a RIC under the Code and intend to continue to qualify each year as a RIC. As a RIC we do not have to pay federal income taxes on our income (including realized gains) that is
distributed to our stockholders, provided that we satisfy certain distribution requirements. Accordingly, we are not permitted under accounting rules to establish reserves for taxes on our unrealized capital gains. If we fail to qualify for RIC
status in any year, to the extent that we had unrealized gains, we would have to establish reserves for taxes, which would reduce our net asset value. In addition, if we, as a RIC, were to decide to make a deemed distribution of net realized capital
gains and retain the net realized capital gains, we would have to establish appropriate reserves for taxes that we would have to pay on behalf of stockholders. It is possible that establishing reserves for taxes could have a material adverse effect
on the value of our common stock.

We will be subject to corporate-level income tax if we are unable to maintain our
qualification as a RIC under Subchapter M of the Code or do not satisfy the annual distribution requirement.

To
maintain RIC status and be relieved of federal taxes on income and gains distributed to our stockholders, we must meet the following annual distribution, income source and asset diversification requirements.



| |  |  | The annual distribution requirement for a RIC will be satisfied if we distribute to our stockholders on an annual basis at least 90% of our net
ordinary income and realized net short-term capital gains in excess of realized net long-term capital losses, if any. Because we may use debt financing, we are subject to an asset coverage ratio requirement under the 1940 Act and we may be subject
to certain financial covenants under our debt arrangements that could, under certain circumstances, restrict us from making distributions necessary to satisfy the distribution requirement. If we are unable to obtain cash from other sources, we could
fail to qualify for RIC tax treatment and thus become subject to corporate-level income tax.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The income source requirement will be satisfied if we obtain at least 90% of our income for each year from dividends, interest, gains from the sale of
stock or securities or similar sources.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The asset diversification requirement will be satisfied if we meet certain asset diversification requirements at the end of each quarter of our taxable
year. To satisfy this requirement, at least 50% of the value of our assets must consist of cash, cash equivalents, U.S. government securities, securities of other RICs, and other acceptable securities; and no more than 25% of the value of our
assets can be invested in the securities, other than U.S. government securities or securities of other RICs, of one issuer, of two or more issuers that are controlled, as determined under applicable Code rules, by us and that are engaged in the
same or similar or related trades or businesses or of certain qualified publicly traded partnerships. Failure to meet these requirements may result in our having to dispose of certain investments quickly in order to prevent the loss of
RIC status. Because most of our investments will be in private companies, and therefore will be relatively illiquid, any such dispositions could be made at disadvantageous prices and could result in substantial losses.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

If we fail to qualify for or maintain RIC status for any reason and are subject to corporate-level income tax, the resulting
corporate-level taxes could substantially reduce our net assets, the amount of income available for distribution and the amount of our distributions. Such a failure would have a material adverse effect on us and our stockholders. The recently
enacted Regulated Investment Company Modernization Act of 2010, which is effective for 2011 and later tax years, provides some relief from RIC disqualification due to failures of the income source and asset diversification requirements,
although there may be additional taxes due in such cases. We cannot assure you that we would qualify for any such relief should we fail the income source or asset diversification requirements.

Risks Relating to an Investment in Our Common Stock

Our shares of common stock have traded at a discount from net asset value and may do so again in the future, which could limit our
ability to raise additional equity capital.

Shares of closed-end investment companies, including BDCs, may trade
at a market discount from net asset value. This characteristic of closed-end investment companies and business development companies is separate and distinct from the risk that our net asset value per share may decline. In the past, the stocks of
BDCs as an industry, including shares of our common stock, have traded below net asset value and at historic lows as a result of concerns over liquidity, leverage restrictions and distribution requirements. When our common stock is trading below its
net asset value per share, we will generally not be able to issue additional shares of our common stock at its market price without first obtaining approval for such issuance from our stockholders and our independent directors. At our 2012 Annual
Meeting of Stockholders, subject to certain conditions and Board of Directors determinations, our stockholders approved our ability to sell or otherwise issue shares of our common stock at a price below its then current net asset value per share for
a twelve month period expiring on the anniversary of the date of stockholder approval.

Investing in our common stock
may involve an above average degree of risk.

The investments we make in accordance with our investment objective may
result in a higher amount of risk than alternative investment options and a higher risk of volatility or loss of principal. Our investments in portfolio companies involve higher levels of risk, and therefore, an investment in our shares may not be
suitable for someone with lower risk tolerance.

The price of our common stock may fluctuate significantly.

As with any company, the price of our common stock will fluctuate with market conditions and other factors. The market
price and liquidity of the market for our common stock may from time to time be affected by a number of factors, which include, but are not limited to, the following:



| |  |  | volatility in the market price and trading volume of common stocks of BDCs or other financial services companies, which are not necessarily related to
the operating performance of these companies;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | investors general perception of our company, the economy and general market conditions;
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | our quarterly results of operations;
| | - |  | ------------------------------------



| |  |  | our origination activity, including the pace of, and competition for, new investment opportunities;
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | the financial performance of the specific industries in which we invest on a recurring basis, including without limitation, our investments in the
business services and healthcare industries;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | announcements of strategic developments, acquisitions and other material events by us or our competitors;
| | - |  | ---------------------------------------------------------------------------------------------------------



| |  |  | changes in regulatory policies or tax guidelines, particularly with respect to RICs or BDCs;
| | - |  | --------------------------------------------------------------------------------------------



| |  |  | loss of RIC status;
| | - |  | -------------------



| |  |  | changes in earnings or variations in operating results;
| | - |  | -------------------------------------------------------



| |  |  | changes in the value of our portfolio of investments;
| | - |  | -----------------------------------------------------



| |  |  | any shortfall in revenue or net income or any increase in losses from levels expected by investors or securities analysts;
| | - |  | --------------------------------------------------------------------------------------------------------------------------



| |  |  | departure of key personnel from the Advisor;
| | - |  | --------------------------------------------



| |  |  | operating performance of companies comparable to us;
| | - |  | ----------------------------------------------------



| |  |  | short-selling pressure with respect to shares of our common stock or BDCs generally;
| | - |  | ------------------------------------------------------------------------------------



| |  |  | general economic trends and other external factors, including price and volume fluctuations in the overall stock market; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------



| |  |  | loss of a major funding source.
| | - |  | -------------------------------

##### Table of Contents

Our shares may trade at discounts from net asset value or at premiums that are
unsustainable over the long term.

Shares of BDCs may trade at a market price that is less than the net asset value
that is attributable to those shares. Our shares have traded above and below our net asset value. The possibility that our shares of common stock will trade at a discount from net asset value or at a premium that is unsustainable over the long term
is separate and distinct from the risk that our net asset value will decrease. It is not possible to predict whether our shares will trade at, above or below net asset value in the future.

Our principal stockholders have substantial ownership in us, and this concentration of ownership could limit your ability to
influence the outcome of key transactions, including a change of control.

As a result of their substantial ownership
in us, our principal stockholders may be able to exert influence over our management and policies. This concentration of ownership may have the effect of delaying, preventing or deterring a change of control of our company, depriving our
stockholders of an opportunity to receive a premium for their common stock as part of a sale of our company, and ultimately affecting the market price of our common stock.

Sales of substantial amounts of our common stock in the public market may have an adverse effect on the market price of our common stock.

The shares of our common stock beneficially owned by our principal stockholders are generally available for resale, subject to the
provisions of Rule 144 promulgated under the Securities Act. Sales of substantial amounts of our common stock, or the availability of such common stock for sale, could adversely affect the prevailing market prices for our common stock. If this
occurs and continues, it could impair our ability to raise additional capital through the sale of securities should we desire to do so.

Our capital-raising activities may have an adverse effect on the market price of our common stock.

When we issue securities or incur debt, we generally obtain cash or cash equivalents. Any increase in our holdings of cash or cash equivalents could adversely affect the prevailing market prices for our
common stock, especially if we are unable to timely deploy the capital in suitable investments. The adverse impact on the prevailing market prices for our common stock could be greater if we issue debt securities or other securities requiring
the payment of interest and are unable to timely deploy the capital in suitable investments.

There is a risk that
investors in our equity securities may not receive dividends or that our dividends may not grow over time.

We intend
to make distributions on a quarterly basis to our stockholders out of assets legally available for distribution. There can be no assurance that we will achieve investment results that will allow us to make a specified level of cash distributions or
year-to-year increases in cash distributions. If we declare a dividend and if more stockholders opt to receive cash distributions rather than participate in our dividend reinvestment plan, we may be forced to sell some of our investments in order to
make cash dividend payments. In addition, due to the asset coverage test applicable to us as a BDC, we may be limited in our ability to make distributions. Further, if we invest a greater amount of assets in equity securities that do not pay current
dividends, it could reduce the amount available for distribution.

We may in the future choose to pay dividends in our
own stock, in which case our stockholders may be required to pay tax in excess of the cash they receive, and which may adversely affect the market price of our common stock.

We may distribute taxable dividends that are payable in part in our stock. Under a recently issued IRS Revenue Procedure, up to 90% of any
such taxable dividend for taxable years ending prior to 2012 could be



39

##### Table of Contents

payable in our stock. The IRS has also issued (and where Revenue Procedure 2009-15 or 2010-12 is not currently applicable, the IRS continues to issue) private letter rulings on cash/stock
dividends paid by regulated investment companies and real estate investment trusts using a 20% cash standard (instead of the 10% cash standard of Revenue Procedures 2009-15 and 2010-12) if certain requirements are satisfied. Taxable stockholders
receiving such dividends will be required to include the full amount of the dividend as ordinary income (or as long-term capital gain to the extent such distribution is properly designated as a capital gain dividend) to the extent of our current and
accumulated earnings and profits for United States federal income tax purposes. As a result, a U.S. stockholder may be required to pay tax with respect to such dividends in excess of any cash received. If a U.S. stockholder sells the stock
it receives as a dividend in order to pay this tax, the sales proceeds may be less than the amount included in income with respect to the dividend, depending on the market price of our stock at the time of the sale. Furthermore, with respect to
non-U.S. stockholders, we may be required to withhold U.S. tax with respect to such dividends, including in respect of all or a portion of such dividend that is payable in stock. In addition, if a significant number of our stockholders
determine to sell shares of our stock in order to pay taxes owed on dividends, it may put downward pressure on the trading price of our stock.

If we issue preferred stock, the net asset value and market value of our common stock may become more volatile.

We cannot assure that the issuance of preferred stock would result in a higher yield or return to the holders of our common stock. The issuance of preferred stock would likely cause the net asset value
and market value of our common stock to become more volatile. If the dividend rate on the preferred stock were to approach the net rate of return on our investment portfolio, the benefit of leverage to the holders of our common stock would be
reduced. If the dividend rate on the preferred stock were to exceed the net rate of return on our portfolio, the leverage would result in a lower rate of return to the holders of common stock than if we had not issued preferred stock. Any decline in
the net asset value of our investment would be borne entirely by the holders of our common stock. Therefore, if the market value of our portfolio were to decline, the leverage would result in a greater decrease in net asset value to the holders of
our common stock than if we were not leveraged through the issuance of preferred stock. This greater net asset value decrease would also tend to cause a greater decline in the market price of our common stock. We might be in danger of failing to
maintain the required asset coverage of the preferred stock or of losing our ratings on the preferred stock or, in an extreme case, our current investment income might not be sufficient to meet the dividend requirements on the preferred stock. In
order to counteract such an event, we might need to liquidate investments in order to fund a redemption of some or all of the preferred stock. In addition, we would pay (and the holders of our common stock would bear) all costs and expenses relating
to the issuance and ongoing maintenance of the preferred stock, including higher incentive fees if our total return exceeds the dividend rate on the preferred stock. Holders of preferred stock may have different interests than holders of common
stock and may at times have disproportionate influence over our affairs.

Holders of any preferred stock we might issue
would have the right to elect members of our Board of Directors and class voting rights on certain matters.

Holders of
any preferred stock we might issue, voting separately as a single class, would have the right to elect two members of our Board of Directors at all times and in the event dividends become two full years in arrears would have the right to elect a
majority of the directors until such arrearage is completely eliminated. In addition, preferred stockholders have class voting rights on certain matters, including changes in fundamental investment restrictions and conversion to open-end status, and
accordingly can veto any changes. Restrictions imposed on the declarations and payment of dividends or other distributions to the holders of our common stock and preferred stock, both by the 1940 Act and by requirements imposed by rating agencies,
might impair our ability to maintain our qualification as a RIC for federal income tax purposes. While we would intend to redeem our preferred stock to the extent necessary to enable us to distribute our income as required to maintain our
qualification as a RIC, there can be no assurance that such actions could be effected in time to meet the tax requirements.

##### Table of Contents

Certain provisions of the Delaware General Corporation Law and our certificate of
incorporation and bylaws could deter takeover attempts and have an adverse impact on the price of our common stock.

The Delaware General Corporation Law, our amended certificate of incorporation and our amended and restated bylaws contain provisions that
may have the effect of discouraging a third party from making an acquisition proposal for us. These anti-takeover provisions may inhibit a change in control in circumstances that could give the holders of our common stock the opportunity to realize
a premium over the market price of our common stock. We have also adopted measures that may make it difficult for a third party to obtain control of us, including provisions of our amended certificate of incorporation and amended and restated
bylaws dividing our board of directors in three classes serving staggered three-year terms, requiring the affirmative vote of the holders of 75% of the then outstanding shares of our capital stock entitled to vote to remove a director for
cause, and, subject to the rights of any holders of preferred stock, filling any vacancy on our Board of Directors only by a vote of a majority of the directors then in office. The classification of our Board of Directors and the limitations on
removal of directors and filling of vacancies could have the effect of making it more difficult for a third party to acquire us, or of discouraging a third party from acquiring us. Our certificate of incorporation and bylaws also provide that
special meetings of the stockholders may only be called by our Board of Directors, Chairman, Chief Executive Officer or Secretary. These provisions, as well as other provisions of our amended certificate of incorporation and our amended and restated
bylaws, may delay, defer or prevent a transaction or a change in control that might otherwise be in the best interests of our stockholders.

Dividends

Our quarterly dividends, if any, are determined by our Board of Directors. Dividends are declared considering our estimate of annual taxable income available for distribution to stockholders and the
amount of taxable income carried over from the prior year for distribution in the current year. We cannot assure stockholders that they will receive any dividends and distributions or dividends and distributions at a particular level. Dividends
declared by the Company since July 25, 2005 (inception of operations) have been as follows:

Tax characteristics of all dividends are reported to stockholders on Form 1099 after the end of the calendar year.

We have elected to be taxed as a RIC under Subchapter M of the Code. In order to maintain favorable RIC tax treatment, we
must distribute annually to our stockholders at least 90% of our ordinary income and realized net short-term capital gains in excess of realized net long-term capital losses, if any, out of the assets legally available for distribution. Under the
Regulated Investment Company Modernization Act of 2010, capital losses incurred by the Company after December 31, 2010 will not be subject to expiration. In addition, such losses must be utilized prior to the losses incurred in the years
preceding enactment. In order to avoid certain excise taxes imposed on RICs, we must distribute during each calendar year an amount at least equal to the sum of:



| |  |  | 98% of our ordinary income for the calendar year;
| | - |  | -------------------------------------------------



| |  |  | 98.2% of our capital gains in excess of capital losses for the one-year period ending on October 31st; and
| | - |  | ----------------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | any ordinary income and net capital gains for preceding years that were not distributed during such years.
| | - |  | ----------------------------------------------------------------------------------------------------------

We may, at our discretion, carry forward taxable income in excess of calendar year distributions and pay a 4% excise tax on this income.
If we choose to do so, all other things being equal, this would increase expenses and reduce the amounts available to be distributed to our stockholders. We will accrue excise tax on estimated taxable income as required. In addition, although we
currently intend to distribute realized net capital gains (i.e., net long-term capital gains in excess of short-term capital losses), if any, at least annually, out of the assets legally available for such distributions, we may in the future decide
to retain such capital gains for investment. There was no provision for federal excise taxes recorded for the year ended December 31, 2012 or for the year ended December 31, 2011. For the year ended December 31, 2010 we recorded a
provision for federal excise taxes of $298,322. There was no undistributed taxable income carried forward from 2012.

We
maintain an opt out dividend reinvestment plan for our common stockholders. As a result, if we declare a dividend, stockholders cash dividends will be automatically reinvested in additional shares of our common stock, unless they
specifically opt out of the dividend reinvestment plan so as to receive cash dividends. With respect to our dividends and distributions paid to stockholders during the years ended December 31, 2012, 2011 and 2010, dividends
reinvested pursuant to our dividend reinvestment plan totaled $5,591,912, $8,021,087 and $5,468,133, respectively.

Under the
terms of an amendment to our dividend reinvestment plan adopted on March 4, 2009, dividends may be paid in newly issued or treasury shares of our common stock at a price equal to 95% of the market price on the dividend payment date. This
feature of the plan means that, under certain circumstances, we may issue shares of our common stock at a price below net asset value per share, which could cause our stockholders to experience dilution.

We may not be able to achieve operating results that will allow us to make dividends and distributions at a specific level or to increase
the amount of these dividends and distributions from time to time. Also, we may be limited in our ability to make dividends and distributions due to the asset coverage test applicable to us as a BDC under the 1940 Act and due to provisions in our
existing and future debt arrangements. If we do not distribute a certain percentage of our income annually, we will suffer adverse tax consequences, including possible loss of favorable RIC tax treatment. In addition, in accordance with GAAP and tax
regulations, we include in income certain amounts that we have not yet received in cash, such as PIK interest, which represents contractual interest added to the loan balance that becomes due at the end of the loan term, or the accrual of original
issue or market discount. Since we may recognize income before or without receiving cash representing such income, we may have difficulty meeting the requirement to distribute at least 90% of our investment company taxable income to obtain tax
benefits as a RIC and may be subject to an excise tax.

With respect to dividends paid to stockholders, certain income we
receive from origination, structuring, closing, commitment and other upfront fees associated with investments in portfolio companies may cause our taxable income to exceed our GAAP income although the differences are expected to be temporary in
nature.

In order to satisfy the annual distribution requirement applicable to RICs, we have the ability to declare a large
portion of a dividend in shares of our common stock instead of in cash. As long as a portion of such dividend is paid in cash (which portion can be as low as 10% for our taxable years ending prior to 2012) and certain requirements are met, the
entire distribution would be treated as a dividend for U.S. federal income tax purposes.

Stock performance graph

The following graph compares the return on our common stock with that of the Standard & Poors 500 Stock Index and the Russell 2000 Index for the period June 27, 2007 (the date our
common stock began to trade on The NASDAQ Global Select Market in connection with our initial public offering) through December 31, 2012. The graph assumes that, on June 27, 2007, a person invested $100 in each of our common stock
(BKCC in the graph), the S&P 500 Index (S&P 500), and the Russell 2000 Index (Russell 2000). The graph measures total shareholder return, which takes into account both changes in stock price and dividends.
It assumes that dividends paid are invested in like securities.

Overview

We were incorporated in Delaware on April 13, 2005 and were
initially funded on July 25, 2005. Our investment objective is to provide a combination of current income and capital appreciation. We intend to invest primarily in debt and equity securities of private and certain public U.S. middle-market
companies.

##### Table of Contents

We are externally managed and have elected to be regulated as a BDC under the 1940 Act. As a
BDC, we are required to comply with certain regulatory requirements. For instance, we generally have to invest at least 70% of our total assets in qualifying assets, including securities of private or thinly traded public U.S. companies,
cash, cash equivalents, U.S. Government securities and high-quality debt investments that mature in one year or less.

Investments

Our level of investment activity can and does vary substantially from period to period depending on many factors, including the amount of debt and equity capital available to middle-market companies, the
level of merger and acquisition activity, the general economic environment and the competitive environment for the types of investments we make.

As a BDC, we generally do not acquire any assets other than qualifying assets specified in the 1940 Act unless, at the time the acquisition is made, at least 70% of our total assets are
qualifying assets (with certain limited exceptions). Qualifying assets include investments in eligible portfolio companies. Under the relevant SEC rules, the term eligible portfolio company includes most private companies,
companies whose securities are not listed on a national securities exchange, and certain public companies that have listed their securities on a national securities exchange and have a market capitalization of less than $250 million. These rules
also permit us to include as qualifying assets certain follow-on investments in companies that were eligible portfolio companies at the time of initial investment but that no longer meet the definition.

Revenues

We generate revenues primarily in the form of interest on the debt we hold, dividends on our equity interests and capital gains on the sale of warrants and other debt or equity interests that we acquire
in portfolio companies. Our investments in fixed income instruments generally have an expected maturity of three to ten years, although we have no lower or upper constraint on maturity, and typically bear interest at a fixed or floating rate.
Interest on our debt securities is generally payable quarterly or semi-annually. In some cases, our debt instruments and preferred stock investments may defer payments of cash interest or dividends or pay interest or dividends in-kind. Any
outstanding principal amount of our debt securities and any accrued but unpaid interest will generally become due at the maturity date. In addition, we may generate revenue in the form of prepayment fees, commitment, origination, capital structuring
or due diligence fees, fees for providing significant managerial assistance.

Expenses

Our primary operating expenses include the payment of a base management fee and, depending on our operating results, an incentive
management fee, interest and credit facility fees, expenses reimbursable under the investment management agreement (the Management Agreement), administration fees and the allocable portion of overhead under the administration agreement.
The base management fee and incentive management fee compensate the Advisor for work in identifying, evaluating, negotiating, closing and monitoring our investments. Our Management Agreement with the Advisor provides that we will reimburse the
Advisor for costs and expenses incurred by the Advisor for office space rental, office equipment and utilities allocable to the Advisor under the Management Agreement, as well as any costs and expenses incurred by the Advisor relating to any
non-investment advisory, administrative or operating services provided by the Advisor to us. We bear all other costs and expenses of our operations and transactions. including those relating to:



| |  |  | our organization;
| | - |  | -----------------



| |  |  | calculating our net asset value (including the cost and expenses of any independent valuation firms);
| | - |  | -----------------------------------------------------------------------------------------------------



| |  |  | expenses incurred by the Advisor payable to third parties in monitoring our investments and performing due diligence on prospective portfolio
companies;

| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Additionally, the Management Agreement provides that the Advisor or its affiliates may be entitled to the Incentive Fee under certain circumstances. The determination of the Incentive Fee will result in
the Advisor or its affiliates receiving no Incentive Fee payments if returns to our stockholders do not meet an 8.0% annualized rate of return and will result in the Advisor or its affiliates receiving less than the full amount of the Incentive Fee
percentage until returns to stockholders exceed an approximate 13.3% annualized rate of return. Annualized rate of return in this context is computed by reference to our net asset value and does not take into account changes in the market price of
our common stock. The determination of the Incentive Fee is subject to any applicable limitations under the 1940 Act and the Advisers Act.

Results of operations

Results comparisons are for the years ended December 31, 2012, 2011 and 2010.

Investment income

Investment income totaled $147,290,596,
$131,502,538 and $105,870,837, respectively, for the years ended December 31, 2012, 2011 and 2010, of which $91,319,290, $73,521,854 and $57,321,456 were attributable to interest and fees on senior secured loans, $52,725,965, $52,922,002 and
$44,042,992 to interest earned on other debt securities, $3,236,501, $4,056,403 and $4,385,525 to dividends from equity securities, $8,840, $26,562 and $8,610 to interest earned on short-term investments and cash equivalents, and zero, $975,717 and
$112,254 to other income, respectively. The increase in investment income compared to the prior year reflects an increase in interest income due to higher average investments held during the period. Although the net portfolio was slightly smaller
than a year ago, the average balance of our total investments at amortized cost was $1,099,285,764 for the current year, compared to $1,021,271,298 for the prior year. The higher average earning asset base as well as the slightly higher weighted
average yields on the comparative portfolios are contributors to the increase in investment income over the prior year.

Expenses

Total expenses for the years ended December 31, 2012, 2011 and 2010 were $73,629,064, $58,623,747 and $45,721,726, respectively, which consisted of $22,504,433, $19,841,258 and $16,877,854 in base
management fees, $19,606,951, $16,561,095 and $6,233,689 in interest expense and fees related to the Credit Facility and Senior Secured Notes, $16,997,054, $11,878,159 and $15,108,049 in incentive management fees from income owed to the Advisor,
$5,494,735, zero and zero in hypothetical incentive management fees from capital gains, $2,524,915, $2,499,742 and $2,136,038 in amortization of debt issuance costs, $1,229,009, $1,905,782 and $877,930 in professional fees, $1,991,416, $1,779,734
and $1,622,957 in Advisor expenses, $528,559, $1,173,754 and $763,876 in administrative services, $496,791, $486,759 and $581,428 in insurance expenses, $467,563, $417,564 and $385,750 in director fees and $1,787,638, $2,079,900 and $1,134,155 in
other expenses, respectively. Incentive management fees for the years ended December 31, 2012, 2011 and 2010 were $22,491,789, $11,878,159 and $15,108,049, respectively. With respect to incentive management fees based on income, $16,997,054,
$11,878,159 and $15,108,049 was earned for the years ended December 31, 2012, 2011 and 2010, respectively. In accordance with GAAP, a hypothetical liquidation is calculated for incentive fees based on gains. It should be noted, however, that a
fee so calculated and accrued is not due and payable, if at all, until the end of each measurement period, or every June 30. Amounts accrued at December 31, 2012, 2011 and 2010 were $5,494,735, zero and zero, respectively.

Net investment income

Net investment income was $73,661,532, $72,878,791 and $59,850,789 respectively, for the years ended December 31, 2012, 2011 and 2010. The increase for the 2012 period is primarily a result of an
increase in interest income and other fees offset by an increase in management fees, incentive fees and interest and debt related expenses.

Net realized gain or loss

Net realized loss of $89,118,419 for the
year ended December 31, 2012 was the result of $87,932,990 in net losses realized from the disposition or restructuring of our investments and $1,185,429 in net loss realized on foreign currency transactions. Net realized loss on investments
resulted primarily from the disposition of our debt

and equity investments in Big Dumpster Acquisition, Inc. et al, American SportWorks LLC et al, and the restructuring of our equity investment in WBS Group Holdings, LLC. Excluding the realization
of the tax provision, nearly the entire net realized loss on investments represents amounts that had been reflected in net unrealized depreciation on investments in prior periods. Foreign currency losses mainly represent net losses on forward
currency contracts used to mitigate the impact that changes in foreign exchange rates would have on our investments denominated in foreign currencies. Net realized loss of $49,893,376 for the year ended December 31, 2011 was the result of
$51,102,184 in net losses realized from the disposition or restructuring of our investments and $1,208,808 in net gain realized on foreign currency transactions. Net realized loss on investments for the year ended December 31, 2011 resulted
primarily from the restructuring or disposition of our investments in Facet Technologies, LLC, Mattress Giant Corporation and Fitness Together Holdings, Inc. Foreign currency gains mainly represent gains on forward currency contracts used to
mitigate the impact that changes in foreign exchange rates would have on our investments denominated in foreign currencies. For the year ended December 31, 2010, net realized loss was $90,236,723 as a result of $89,301,764 in net losses realized
from the disposition or restructuring of our investments and $934,959 in net loss realized on foreign currency transactions.

Net unrealized appreciation or depreciation

For the years ended December 31, 2012, 2011 and 2010, the change in net unrealized appreciation or depreciation was an increase in net unrealized appreciation of $72,808,120, $53,935,094 and
$101,935,495, respectively. The increase in net unrealized appreciation for the year ended December 31, 2012 was comprised of a increase in net unrealized appreciation on investments of $71,335,341 and a net foreign currency translation gain of
$1,472,779. The change was a mainly a result of the reversal of previously reported accumulated unrealized depreciation realized during the period. The decrease in net unrealized depreciation for the year ended December 31, 2011 was comprised
of a decrease in net unrealized depreciation on investments of $54,695,534 and a net foreign currency translation loss of $760,440. The decrease in net unrealized depreciation for the year ended December 31, 2010 was comprised of a decrease in
net unrealized depreciation on investments of $102,486,118 and net foreign currency translation loss of $550,623.

Net
increase in net assets resulting from operations

The net increase in net assets resulting from operations was
$57,351,233, $76,920,509 and $71,549,561 for the years ended December 31, 2012, 2011 and 2010, respectively. The change primarily reflects the increase in net investment income offset by net realized and unrealized losses, for the year
ended December 31, 2012.

Financial condition, liquidity and capital resources

During the year ended December 31, 2012, we generated operating cash flows primarily from interest earned and fees received on senior
secured loans and other debt securities, as well as from sales of selected portfolio company investments or repayments of principal.

Net cash provided by operating activities for the year ended December 31, 2012 was $68,317,312. Our primary sources of cash from operating activities during the period consisted of a net increase in
net assets from operations of $57,351,233 and sales/repayments of investments of $314,755,655, net of purchases of investments of $317,097,868.

Net cash used in financing activities for the year ended December 31, 2012 was $66,974,560. Our primary use of cash for financing activities was $70,824,560 of dividend distributions offset by
proceeds from net borrowings under the Credit Facility.

Our senior secured, multi-currency Credit Facility provides us with
$375,000,000 in total availability, consisting of $275,000,000 of revolving loan commitments and $100,000,000 of term loan commitments. The Credit Facility is secured by substantially all of the assets in the Companys portfolio, including cash
and cash

equivalents. The Credit Facility has a stated maturity date of December 6, 2013 and the interest rate applicable to borrowings thereunder is generally LIBOR plus an applicable spread of
either 3.00% or 3.25% for revolving loans, based on a pricing grid depending on the Companys credit rating, and LIBOR plus 3.00% for term loans. The Credit Facility does not contain a LIBOR floor requirement. At December 31, 2012, the
effective LIBOR spread under the Credit Facility was 3.10%. Term loan commitments under the Credit Facility have been fully drawn and, once repaid, may not be reborrowed. The Credit Facility also includes an accordion feature that allows
the Company, under certain circumstances, to increase the size of the Credit Facility by up to an additional $275,000,000 of revolving loan commitments and $250,000,000 of term loan commitments. The Credit Facility is used to supplement the
Companys equity capital to make additional portfolio investments and for other general corporate purposes. At December 31, 2012, we had $171,850,000 drawn and outstanding under the Credit Facility, with $203,150,000 available to us,
subject to compliance with customary affirmative and negative covenants, including the maintenance of a minimum stockholders equity, the maintenance of a ratio of not less than 200% of total assets (less total liabilities other than
indebtedness) to total indebtedness, and restrictions on certain payments and issuance of debt. At December 31, 2012, the Company was in compliance with regulatory coverage requirements with an asset coverage ratio of approximately 295% and was
in compliance with all financial covenants under our debt agreements. In addition, borrowings under the Credit Facility (and the incurrence of certain other permitted debt) are subject to compliance with a borrowing base that applies different
advance rates to different types of assets in the Companys portfolio.

In January 2011, the Company closed a
private placement issuance of $158,000,000 in aggregate principal amount of Senior Secured Notes with a fixed interest rate of 6.50% and a maturity date of January 18, 2016 and $17,000,000 in aggregate principal amount of Senior Secured Notes
with a fixed interest rate of 6.60% and a maturity date of January 18, 2018. Interest on the Senior Secured Notes is due semi-annually on January 18 and July 18, commencing on July 18, 2011. The proceeds from the issuance of the
Senior Secured Notes were used to fund new portfolio investments, reduce outstanding borrowings under the Credit Facility and for general corporate purposes. The Senior Secured Notes contain customary affirmative and negative covenants substantially
similar to those in our Credit Facility. At December 31, 2012, we were in compliance with all financial and operational covenants required by the Credit Facility and Senior Secured Notes.

On February 19, 2013 the Company closed a private offering of $100,000,000 in aggregate principal amount of its 5.50% unsecured
convertible senior notes due 2018. The initial purchasers of the Notes fully exercised their overallotment option and purchased an additional $15,000,000 in aggregate principal amount of the Notes. The closing of the overallotment option took place
on March 4, 2013. With the exercise of the overallotment option, a total of $115,000,000 in aggregate principal amount of the Notes have been sold. Net proceeds to the Company from the offering, including the exercise of the overallotment option,
are approximately $111,300,000. The Notes were only offered to qualified institutional buyers as defined in the Securities Act of 1933, as amended (the Securities Act) pursuant to Rule 144A under the Securities Act.

The Notes are unsecured and bear interest at a rate of 5.50% per year, payable semi-annually in arrears. In certain circumstances
and during certain periods, the Notes are convertible into cash, shares of BlackRock Kelso Capitals common stock or a combination of cash and shares of the Companys common stock, at the Companys election, at an initial conversion
rate of 86.0585 shares of common stock per $1,000 principal amount of the Notes, which is equivalent to an initial conversion price of approximately $11.62 per share of the Companys common stock, subject to defined anti-dilution adjustments.
The Company does not have the right to redeem the Notes prior to maturity. The Notes mature on February 15, 2018, unless repurchased or converted in accordance with their terms prior to such date.

As a closed-end investment company regulated as a BDC under the 1940 Act, we are prohibited from selling shares of our common stock at a
price below the current net asset value of the stock, or NAV, unless our stockholders approve such a sale and our Board of Directors makes certain determinations. On February 8, 2010, subject to certain Board of Director determinations, our
stockholders approved our ability to sell or otherwise

issue shares of our common stock at a price below its then current net asset value per share for a twelve month period expiring on the anniversary of the date of stockholder approval. In any such
case, the price at which our common stock would be issued and sold may not be less than a price that, in the determination of our Board of Directors, closely approximates the market value of such common stock. Any sale of the Companys common
stock at a price below NAV would have a dilutive effect on our NAV.

We have entered into several contracts under which we have future commitments. Pursuant to the Management Agreement, the Advisor manages
our day-to-day operations and provides investment advisory services to us. Payments under the Management Agreement are equal to a percentage of the value of our gross investment assets and an incentive management fee, plus reimbursement of certain
expenses incurred by the Advisor. Under our administration agreement, the Administrator provides us with certain administrative services, facilities and personnel. Payments under the administration agreement are equal to an allocable portion of
overhead and other expenses incurred by the Administrator in performing its obligations to us, including rent and our allocable portion of the cost of certain of our officers and their respective staffs. Pursuant to various other agreements,
subsidiaries of The Bank of New York Mellon Corporation provide custodian services, administrative and accounting services, transfer agency and compliance support services to us. Payments under such agreements are generally equal to a percentage of
our average net assets plus reimbursement of reasonable expenses, and a base fee. Either party may terminate each of the Management Agreement, administration agreement and such other agreements without penalty upon not less than 60 days
written notice to the other.

Off-balance sheet financing

In the normal course of business, the Company may enter into guarantees on behalf of portfolio companies. Under these arrangements, the
Company would be required to make payments to third parties if the portfolio companies were to default on their related payment obligations. The Companys only such guarantee outstanding at December 31, 2010 was terminated on
January 17, 2011 with no payments having been made thereunder. There were no such guarantees outstanding at December 31, 2012 or 2011.

Tax characteristics of all dividends are reported to stockholders on Form 1099 after the end of the calendar year.

We have elected to be taxed as a RIC under Subchapter M of the Code. In order to maintain favorable RIC tax treatment, we
must distribute annually to our stockholders at least 90% of our ordinary income and realized net short-term capital gains in excess of realized net long-term capital losses, if any, out of the assets legally available for distribution. Under the
Regulated Investment Company Modernization Act of 2010, capital losses incurred by the Company after December 31, 2010 will not be subject to expiration. In addition, such losses must be utilized prior to the losses incurred in the years
preceding enactment. In order to avoid certain excise taxes imposed on RICs, we must distribute during each calendar year an amount at least equal to the sum of:



| |  |  | 98% of our ordinary income for the calendar year;
| | - |  | -------------------------------------------------



| |  |  | 98.2% of our capital gains in excess of capital losses for the one-year period ending on October 31st; and
| | - |  | ----------------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | any ordinary income and net capital gains for preceding years that were not distributed during such years.
| | - |  | ----------------------------------------------------------------------------------------------------------

We may, at our discretion, carry forward taxable income in excess of calendar year distributions and pay a 4% excise tax on this income.
If we choose to do so, all other things being equal, this would increase expenses and reduce the amounts available to be distributed to our stockholders. We accrue excise tax on estimated taxable income as required. In addition, although we
currently intend to distribute realized net capital gains (i.e., net long-term capital gains in excess of short-term capital losses), if any, at least annually, out of the assets legally available for such distributions, we may in the future decide
to retain such capital gains for investment. There was no provision for federal excise taxes recorded for the years ended December 31, 2012 and 2011. For the year ended December 31, 2010 we recorded a provision for federal excise taxes of
$298,322. There was no undistributed taxable income carried forward from 2012.

We maintain an opt out dividend
reinvestment plan for our common stockholders. As a result, if we declare a dividend, stockholders cash dividends will be automatically reinvested in additional shares of our common stock, unless they specifically opt out of the
dividend reinvestment plan so as to receive cash dividends. With respect to our dividends and distributions paid to stockholders during the years ended December 31, 2012, 2011 and 2010, dividends reinvested pursuant to our dividend reinvestment
plan totaled $5,591,912, $8,021,087 and $5,468,133, respectively.

Under the terms of an amendment to our dividend
reinvestment plan adopted on March 4, 2009, dividends may be paid in newly issued or treasury shares of our common stock at a price equal to 95% of the market price on the dividend payment date. This feature of the plan means that, under
certain circumstances, we may issue shares of our common stock at a price below net asset value per share, which could cause our stockholders to experience dilution.

We may not be able to achieve operating results that will allow us to make dividends and distributions at a specific level or to increase the amount of these dividends and distributions from time to time.
Also, we may be limited in our ability to make dividends and distributions due to the asset coverage test applicable to us as a BDC under the 1940 Act and due to provisions in our existing and future debt arrangements. If we do not distribute a
certain percentage of our income annually, we will suffer adverse tax consequences, including possible loss of favorable RIC tax treatment. In addition, in accordance with U.S. generally accepted accounting principles and tax regulations, we include
in income certain amounts that we have not yet received in cash, such as PIK interest or the accrual of original issue or market discount. Since we may recognize income before or without receiving cash representing such income, we may have
difficulty meeting the requirement to distribute at least 90% of our investment company taxable income to obtain tax benefits as a RIC and may be subject to an excise tax. In order to satisfy the annual distribution requirement applicable to RICs,
we have the ability to declare a large portion of a dividend in shares of our common stock instead of in cash. As long as a portion of such dividend is paid in cash (which portion can be as low as 10% for our taxable years ending prior to 2012) and
certain requirements are met, the entire distribution would be treated as a dividend for U.S. federal income tax purposes.

With respect to dividends paid to stockholders, certain income we receive from origination, structuring, closing, commitment and other
upfront fees associated with investments in portfolio companies may cause our taxable income to exceed our GAAP income although the differences are expected to be temporary in nature.

Recent developments

On February 19, 2013 the Company closed a private
offering of $100 million in aggregate principal amount of 5.50% unsecured convertible senior notes due 2018. The initial purchasers of the Notes fully exercised their overallotment option and purchased an additional $15 million in aggregate
principal amount of the Notes. The closing of the overallotment option took place on March 4, 2013. With the exercise of the overallotment option, a total of $115 million in aggregate principal amount of the Notes have been sold. Net proceeds to the
Company from the offering, including the exercise of the overallotment option,

are approximately $111.3 million. The Notes were only offered to qualified institutional buyers as defined in the Securities Act pursuant to Rule 144A under the Securities Act.

The Notes are unsecured and bear interest at a rate of 5.50% per year, payable semi-annually in arrears. In certain circumstances
and during certain periods, the Notes are convertible into cash, shares of BlackRock Kelso Capitals common stock or a combination of cash and shares of the Companys common stock, at the Companys election, at an initial conversion
rate of 86.0585 shares of common stock per $1,000 principal amount of the Notes, which is equivalent to an initial conversion price of approximately $11.62 per share of the Companys common stock, subject to defined anti-dilution adjustments.
The Company does not have the right to redeem the Notes prior to maturity. The Notes mature on February 15, 2018, unless repurchased or converted in accordance with their terms prior to such date.

On March 6, 2013 our Board of Directors declared a dividend of $0.26 per share, payable on April 2, 2013 to stockholders of
record at the close of business on March 19, 2013.

Notice is hereby given in accordance with Section 23(c) of the
1940 Act that from time to time the Company may purchase shares of its common stock in the open market at prevailing market prices.



|Item 7A. | Quantitative and Qualitative Disclosure About Market Risk
|-------- | ---------------------------------------------------------

We are subject to financial market risks, including changes in interest rates. At December 31, 2012, 45% of our debt investments bore interest based on floating rates, such as LIBOR, the Federal
Funds Rate or the Prime Rate. The interest rates on such investments generally reset by reference to the current market index after one to six months. At December 31, 2012, the percentage of our total debt investments that bore floating rate
interest subject to an interest rate floor was 40%. Floating rate investments subject to a floor generally reset by reference to the current market index after one to six months only if the index exceeds the floor.

While hedging activities may help to insulate us against adverse changes in interest rates, they also may limit our ability to
participate in the benefits of lower interest rates with respect to our portfolio of investments. During the years ended December 31, 2012, 2011 and 2010, we did not engage in any interest rate hedging activity.

(b) Managements Report on Internal Control Over Financial Reporting.The Companys
management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act). Under the supervision and with the participation of management,
including the Chief Executive Officer and Chief Financial Officer, the Company conducted an evaluation of the effectiveness of the Companys internal control over financial reporting based on the criteria established in Internal
ControlIntegrated Frameworkissued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on the Companys evaluation under the framework in Internal ControlIntegrated Framework, management
concluded that the Companys internal control over financial reporting was effective as of December 31, 2012. The Companys internal control over financial reporting as of December 31, 2012 has been audited by our independent
registered public accounting firm, Deloitte & Touche LLP, as stated in its report titled Report of Independent Registered Public Accounting Firm on the following page.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of

BlackRock Kelso Capital Corporation:

We have audited the internal control over financial reporting of BlackRock Kelso Capital Corporation and subsidiaries (the Company) as of December 31, 2012, based on criteria established
in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Companys management is responsible for maintaining effective internal control over financial reporting and
for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Managements Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the
Companys internal control over financial reporting based on our audit.

We conducted our audit in accordance with the
standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance whether effective internal control over financial reporting was maintained in all
material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control
based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A companys internal control over financial reporting is a process designed by, or under the supervision of, the companys
principal executive and principal financial officers, or persons performing similar functions, and effected by the companys board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of
financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A companys internal control over financial reporting includes those policies and procedures that
(1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as
necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors
of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the companys assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or
improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to
future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of
December 31, 2012, based on the criteria established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated
statement of assets and liabilities, including the consolidated schedule of investments, as of December 31, 2012, and the related consolidated statements of operations, changes in net assets, cash flows and financial highlights for the year
then ended of the Company and our report dated March 6, 2013 expressed an unqualified opinion on those consolidated financial statements.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of

BlackRock Kelso Capital Corporation:

We have audited the accompanying
consolidated statements of assets and liabilities of BlackRock Kelso Capital Corporation and subsidiaries (the Company), including the consolidated schedules of investments, as of December 31, 2012 and 2011, and the related
consolidated statements of operations, changes in net assets, and cash flows for each of the three years in the period ended December 31, 2012 and the consolidated financial highlights for each of the five years in the period then ended.
These consolidated financial statements and consolidated financial highlights are the responsibility of the Companys management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United
States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement
presentation. Our procedures included confirmation of investments as of December 31, 2012 and 2011, by correspondence with the custodian, loan agents or borrowers; where replies were not received, we performed other auditing procedures. We
believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements
and consolidated financial highlights referred to above present fairly, in all material respects, the financial position of BlackRock Kelso Capital Corporation and subsidiaries as of December 31, 2012 and 2011, and the results of their
operations, changes in their net assets, and their cash flows for each of the three years in the period ended December 31, 2012 and the financial highlights for each of the five years in the period then ended, in conformity with accounting
principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the
Public Company Accounting Oversight Board (United States), the Companys internal control over financial reporting as of December 31, 2012, based on the criteria established inInternal ControlIntegrated Framework issued by
the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 6, 2013 expressed an unqualified opinion on the Companys internal control over financial reporting.

| | (d) | Security is exempt from registration under Rule 144A of the Securities Act of 1933. Such securities may be resold in transactions that are exempt from registration,
normally to qualified institutional buyers. In the aggregate, these securities represent 12.8% of the Companys net assets at December 31, 2011.

London Interbank Offered Rate (LIBOR) or other base rate (commonly the Federal Funds Rate or the Prime Rate), at the borrowers option. In addition, approximately 58% of such senior secured loans have floors of 1.00% to 3.25%. The borrower
under a senior secured loan generally has the option to select from interest reset periods of one, two, three or nine months and may alter that selection at the end of any reset period. The stated interest rate represents the weighted average
interest rate at December 31, 2011 of all contracts within the specified loan facility.

BlackRock Kelso Capital Corporation

Notes to Consolidated Financial Statements

1. Organization

BlackRock Kelso Capital Corporation and subsidiaries (the
Company) was organized as a Delaware corporation on April 13, 2005 and was initially funded on July 25, 2005. The Company has elected to be regulated as a business development company (BDC) under the Investment
Company Act of 1940 (the 1940 Act). In addition, for tax purposes the Company has qualified and has elected to be treated as a regulated investment company (RIC) under the Internal Revenue Code of 1986 (the Code).
The Companys investment objective is to generate both current income and capital appreciation through debt and equity investments. The Company invests primarily in middle-market companies in the form of senior and junior secured and unsecured
debt securities and loans, each of which may include an equity component, and by making direct preferred, common and other equity investments in such companies.

On July, 25, 2005, the Company completed a private placement of 35,366,589 shares of its common stock at a price of $15.00 per share receiving net proceeds of approximately $529 million. On July 2,
2007, the Company completed an initial public offering through which it sold an additional 10,000,000 shares of its common stock at a price of $16.00 per share and listed its shares on the NASDAQ Global Select Market.

The accompanying consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United
States of America (GAAP).

2. Significant accounting policies

Basis of Presentation

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date
of the consolidated financial statements and the reported amounts of income and expenses during the reported period. Changes in the economic environment, financial markets and any other parameters used in determining these estimates could cause
actual results to differ and such differences could be material.

The accompanying consolidated financial statements include
the accounts of the Company and its subsidiaries, which were established to hold certain investments of the Company. The Company owns 100% of each subsidiary and, as such, the subsidiaries are consolidated into the Companys consolidated
financial statements. The subsidiaries hold investments which are treated as pass through entities for tax purposes. By investing through these 100% owned subsidiaries, the Company is able to benefit from corporate tax treatment for these entities
and thereby create a tax structure that is more advantageous with respect to the RIC status of the Company. Transactions between subsidiaries, to the extent they occur, are eliminated in consolidation.

Expenses are recorded on an accrual basis.

Investments

Security transactions are accounted for on the trade
date unless there are substantial conditions to the purchase. Realized gains or losses are measured by the difference between the net proceeds from the repayment or sale and the amortized cost basis of the investment. Unrealized gains or losses
primarily reflect the change in investment values, including the reversal of previously recorded unrealized gains or losses when gains or losses are realized. Realized gains or losses on the disposition of investments are calculated using the
specific identification method.

##### Table of Contents

Investments for which market quotations are readily available are valued at such market
quotations unless they are deemed not to represent fair value. The Company obtains market quotations, when available, from an independent pricing service or one or more broker-dealers or market makers and utilizes the average of the range of bid and
ask quotations. Debt and equity securities for which market quotations are not readily available or for which market quotations are deemed not to represent fair value are valued at fair value as determined in good faith by or under the direction of
the Companys Board of Directors.

Because the Company expects that there will not be a readily available market for
substantially all of the investments in its portfolio, the Company expects to value substantially all of its portfolio investments at fair value as determined in good faith by or under the direction of the Board of Directors using a consistently
applied valuation process in accordance with a documented valuation policy that has been reviewed and approved by the Board of Directors. Due to the inherent uncertainty and subjectivity of determining the fair value of investments that do not have
a readily available market value, the fair value of the Companys investments may differ significantly from the values that would have been used had a readily available market value existed for such investments and may differ materially from
the values that the Company may ultimately realize.

In addition, changes in the market environment and other events may have
differing impacts on the market quotations used to value some of the Companys investments than on the fair values of the Companys investments for which market quotations are not readily available. Market quotations may be deemed not to
represent fair value in certain circumstances where BlackRock Kelso Capital Advisors LLC, the Companys investment advisor (the Advisor), believes that facts and circumstances applicable to an issuer, a seller or purchaser or the
market for a particular security cause current market quotations to not reflect the fair value of the security. Examples of these events could include cases where a security trades infrequently causing a quoted purchase or sale price to become
stale, where there is a forced sale by a distressed seller, where market quotations vary substantially among market makers, or where there is a wide bid-ask spread or significant increase in the bid-ask spread.

With respect to the Companys investments for which market quotations are not readily available or for which market quotations are
deemed not to represent fair value, the Board of Directors has approved a multi-step valuation process applied each quarter, as described below:



|(i) | The quarterly valuation process begins with each portfolio company or investment being initially evaluated and rated by the investment
professionals of the Advisor responsible for the portfolio investment;
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(ii) | The investment professionals provide recent portfolio company financial statements and other reporting materials to independent valuation firms
engaged by the Board of Directors, such firms conduct independent appraisals each quarter and their preliminary valuation conclusions are documented and discussed with senior management of the Advisor;
|---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(iii) | The audit committee of the Board of Directors reviews the preliminary valuations prepared by the independent valuation firms; and
|----- | ---------------------------------------------------------------------------------------------------------------------------------



|(iv) | The Board of Directors discusses valuations and determines the fair value of each investment in the portfolio in good faith based on the input
of the Advisor, the respective independent valuation firms and the audit committee.

##### Table of Contents

Those investments for which market quotations are not readily available or
for which market quotations are deemed not to represent fair value are valued utilizing a market approach, an income approach, or both approaches, as appropriate. The market approach uses prices and other relevant information generated by market
transactions involving identical or comparable assets or liabilities (including a business). The income approach uses valuation techniques to convert future amounts (for example, cash flows or earnings) to a single present amount (discounted). The
measurement is based on the value indicated by current market expectations about those future amounts. In following these approaches, the types of factors that the Company may take into account in determining the fair value of its investments
include, as relevant and among other factors: available current market data, including relevant and applicable market trading and transaction comparables, applicable market yields and multiples, security covenants, call protection provisions,
information rights, the nature and realizable value of any collateral, the portfolio companys ability to make payments, (e.g. non-performance risk), its earnings and discounted cash flows, the markets in which the portfolio company does
business, comparisons of financial ratios of peer companies that are public, M&A comparables, the Companys principal market (as the reporting entity) and enterprise values.

Until the end of the second calendar quarter following its acquisition, each unquoted investment in a new portfolio
company generally is held at amortized cost, which the Advisor believes approximates fair value under the circumstances. As of that date, an independent valuation firm conducts an initial independent appraisal of the investment.

Accounting Standards Codification (ASC) 820-10, Fair Value Measurements and Disclosures
(ASC 820-10), issued by the Financial Accounting Standards Board (FASB), defines fair value, establishes a framework for measuring fair value and requires disclosures about fair value measurements. See note 10 for
further details.

Cash and Cash Equivalents

Cash equivalents include short-term liquid overnight investments.

Revenue recognition

Interest income is recorded on an accrual basis and includes amortization of premiums and accretion of discounts. Discounts and premiums to par value on securities purchased are accreted/amortized into
interest income over the life of the respective security. Premiums and discounts are determined based on the cash flows expected to be received for a particular investment upon maturity.

Dividend income is recorded on the ex-dividend date and is adjusted to the extent that the Company expects to collect such amounts. For
loans and securities with payment-in-kind (PIK) income, which represents contractual interest or dividends accrued and added to the principal balance and generally due at maturity, such income is accrued only to the extent that the
Advisor believes that the PIK income is likely to be collected. To maintain the Companys status as a RIC, this non-cash source of income must be paid out to stockholders in the form of dividends, even though the Company has not yet collected
the cash.

Fee income, such as structuring fees, origination, closing, commitment and other upfront fees are generally
non-recurring and are recognized as revenue when earned. In instances where the Company does not perform significant services in connection with the related investment, fees paid to the Company may be deferred and amortized over the estimated life
of the investment. Upon the prepayment of a loan or debt security, any prepayment penalties and unamortized loan origination, structuring, closing, commitment and other upfront fees are recorded as income.

##### Table of Contents

U.S. Federal income taxes

The Company has elected to be treated as a RIC under Subchapter M of the Code and operates in a manner so as to qualify for the tax
treatment applicable to RICs.

In order to qualify for favorable tax treatment as a RIC, the Company is required to distribute
annually to its stockholders at least 90% of its investment company taxable income, as defined by the Code. To avoid federal excise taxes, we must distribute annually at least 98% of our ordinary income and 98.2% of net capital gains from the
current year and any undistributed ordinary income and net capital gains from the preceding years. The Company, at its discretion, may carry forward taxable income in excess of calendar year distributions and pay a 4% excise tax on this income. If
the Company chooses to do so, all other things being equal, this would increase expenses and reduce the amount available to be distributed to stockholders. The Company will accrue excise tax on estimated undistributed taxable income as required.

Dividends from net investment income and distributions from net realized capital gains are determined in accordance with U.S.
federal income tax regulations, which may differ from those amounts determined in accordance with GAAP. These book/tax differences are either temporary or permanent in nature. To the extent these differences are permanent, they are charged or
credited to paid-in-capital or accumulated net realized gain (loss), as appropriate, in the period that the differences arise. Temporary and permanent differences are primarily attributable to differences in the tax treatment of certain loans and
the tax characterization of income and non-deductible expenses. These differences are generally determined in conjunction with the preparation of the Companys annual RIC tax return.

Book and tax basis differences relating to stockholder dividends and distributions and other permanent book and tax differences are
reclassified among the Companys capital accounts. In addition, the character of income and gains to be distributed is determined in accordance with income tax regulations that may differ from GAAP.

The Company may pay distributions in excess of its taxable net investment income. This excess would be a tax-free return of capital in
the period and reduce the shareholders tax basis in its shares. The cumulative amount is disclosed on the Consolidated Statements of Assets and Liabilities as distributions in excess of taxable net investment income. Cumulative distributions
in excess of taxable net investment income are $22,291,022 and $26,165,703 as of December 31, 2012 and December 31, 2011, respectively.

Dividends to Common Stockholders

Dividends and distributions to
common stockholders are recorded on the ex-dividend date. The amount to be paid out as a dividend is determined by the Board of Directors. Net realized capital gains, if any, generally are distributed at least annually, although the Company may
decide to retain such capital gains for investment.

The Company has adopted a dividend reinvestment plan that provides for
reinvestment of distributions on behalf of stockholders, unless a stockholder elects to receive cash. As a result, if the Board of Directors authorizes, and the Company declares, a cash dividend, then stockholders who have not opted out
of the dividend reinvestment plan will have their cash dividends automatically reinvested in additional shares of Common Stock, rather than receiving the cash dividends.

##### Table of Contents

Foreign Currency

Foreign currency amounts are translated into United States dollars on the following basis:



|(i) | market value of investment securities, other assets and liabilitiesat the spot exchange rate on the last business day of the period; and
|--- | -----------------------------------------------------------------------------------------------------------------------------------------



|(ii) | purchases and sales of investment securities, income and expensesat the rates of exchange prevailing on the respective dates of such
transactions, income or expenses.
|---- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------

Although net assets and fair values are presented based on the applicable
foreign exchange rates described above, the Company does not isolate that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in fair values of investments
held. Such fluctuations are included with the net realized and unrealized gain or loss from investments.

Investments
denominated in foreign currencies and foreign currency transactions may involve certain considerations and risks not typically associated with those of domestic origin, including unanticipated movements in the value of the foreign currency relative
to the U.S. dollar.

Debt Issuance Costs

Debt issuance costs are amortized over the term of the related debt using the straight line method.

Equity Offering Expenses

The Company records registration expenses related to its shelf registration statement and related SEC filings as prepaid assets. These expenses are charged as a reduction of capital upon utilization, in
accordance with ASC 946, Financial ServicesInvestment Companies.

Non-Accrual Loans

Loans or debt securities are placed on non-accrual status, as a general matter, when principal or interest payments are past due 30 days
or more or when there is reasonable doubt that principal or interest will be collected. Accrued interest generally is reversed when a loan or debt security is placed on non-accrual status. Interest payments received on non-accrual loans or debt
securities may be recognized as income or applied to principal depending upon managements judgment. Non-accrual loans and debt securities are restored to accrual status when past due principal and interest is paid and, in managements
judgment, are likely to remain current. The Company may make exceptions to this treatment if the loan has sufficient collateral value and is in the process of collection.

Recently Issued Accounting Pronouncements

In May 2011, the FASB
issued ASU 2011-04, Fair Value Measurement: Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs(ASU 2011-04), which amends the existing fair value guidance within ASC 820-10. The
amendments include: (1) application of the concepts of highest and best use and valuation premise only to measuring the fair value of nonfinancial assets (that is, it does not apply to financial assets or any liabilities), (2) an exception
to fair value measurement principles for financial assets and financial liabilities (and derivatives) with offsetting positions in market risks or counterparty credit risk, which allows an entity to measure the fair value of the net risk position,
when several criteria are met, (3) extension of the prohibition of a blockage factor application to all fair value measurements, (4) a model for the fair value measurement of instruments classified within an entitys
shareholders equity which is consistent with the guidance of measuring the fair value for liabilities, (5) additional disclosures for fair value measurements categorized in Level 3 of the fair value hierarchy: (i) quantitative
information about unobservable

inputs used, (ii) a description of the valuation processes used by the entity and (iii) a qualitative discussion about the sensitivity of the measurements, (6) disclosure of the
level in the fair value hierarchy of assets and liabilities not recorded at fair value but where fair value is disclosed and (7) disclosure of any transfers between Levels 1 and 2 of the fair value hierarchy, not just significant transfers. The
provisions of ASU 2011-04 were effective for the Company on January 1, 2012. Management has adopted the provisions of ASU 2011-04 on January 1, 2012. The adoption of ASU 2011-04 did not have an impact on the measurement of fair value of
the Companys investments, but did impact the Companys disclosures related to fair value, which have been reflected in the notes to these consolidated financial statements.

In December 2011, the FASB issued ASU 2011-11, Disclosures about Offsetting Assets and Liabilities (ASU 2011-11).
These disclosure requirements are intended to help investors and other financial statement users to better assess the effect or potential effect of offsetting arrangements on an entitys financial position. They also improve transparency in the
reporting of how companies mitigate credit risk, including disclosure of related collateral pledged or received. In addition, ASU 2011-11 facilitates comparison between those entities that prepare their financial statements on the basis of U.S.
GAAP and those entities that prepare their financial statements on the basis of IFRS. ASU 2011-11 requires entities to disclose both gross and net information about both instruments and transactions eligible for offset in the financial
position; and to disclose instruments and transactions subject to an agreement similar to a master netting agreement. ASU 2011-11 is effective for fiscal years beginning on or after January 1, 2013, and interim periods within those annual
periods. Management is currently evaluating the implications of ASU 2011-11 and its impact on financial statement disclosures.

In January 2013, the FASB issued ASU 2013-01, Balance Sheet (Topic 210): Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities (ASU 2013-01). This update
clarifies that the scope of ASU 2011-11 applies to derivatives accounted for in accordance with Topic 815. This update is effective for the Company for the year ending December 31, 2013, and is not expected to have a material effect on the
Companys consolidated financial statements.

3. Agreements and related party transactions

Base Management Fee

The Company has entered into an investment management agreement (the Management Agreement) with the Advisor, under which the Advisor, subject to the overall supervision of the Companys
Board of Directors, manages the day-to-day operations of, and provides investment advisory services to, the Company. For providing these services, the Advisor receives a base management fee (the Management Fee) from the Company quarterly
in arrears at an annual rate of 2.0% of the Companys total assets, including any assets acquired with the proceeds of leverage.

For the years ended December 31, 2012, 2011 and 2010, the Advisor earned $22,504,433, $19,841,258 and $16,877,854, respectively, in base management fees under the Management Agreement.

Incentive Management Fee

The Management Agreement provides that the Advisor or its affiliates may be entitled to an incentive management fee (the Incentive Fee) under certain circumstances. The determination of the
Incentive Fee, as described in more detail below, will result in the Advisor or its affiliates receiving no Incentive Fee payments if returns to Company stockholders do not meet an 8.0% annualized rate of return during the applicable fee measurement
period, and will result in the Advisor or its affiliates receiving less than the full amount of the Incentive Fee percentage until returns to stockholders exceed an approximate 13.3% annualized rate of return during such period. Annualized rate of
return in this context is computed by reference to the Companys net asset value and does not take into account changes in the market price of the Companys common stock.



F-28

##### Table of Contents

The Advisor will be entitled to receive the Incentive Fee if the Companys performance
exceeds a hurdle rate during different measurement periods: trailing four quarters periods (which applies only to the portion of the Incentive Fee based on income) and annual periods (which applies only to the portion of the
Incentive Fee based on capital gains). The trailing four quarters periods for purposes of determining the income portion of the Incentive Fee payable for the three months ended December 31, 2012 and 2011 was determined by
reference to the four quarter periods ended on December 31, 2012 and 2011, respectively. The term annual period means the period beginning on July 1 of each calendar year and ending on June 30 of the next calendar year.

The hurdle rate for each measurement period is 2.0% multiplied by the Companys net asset values at the beginning of
each calendar quarter during the measurement period, calculated after giving effect to any distributions that occurred during the measurement period. A portion of the Incentive Fee is based on the Companys income and a portion is based on
capital gains. Each portion of the Incentive Fee is described below.

Quarterly Incentive Fee Based on Income.
For each trailing four quarters period, the Company pays the Advisor an Incentive Fee based on the amount by which (A) aggregate distributions and amounts distributable out of taxable net income (excluding any capital gain and loss)
during the period less the sum of, if negative, net unrealized capital appreciation/(depreciation) and net realized capital gains/(losses) during the period, in excess of (B) the hurdle rate for the period. The amount of the excess of
(A) over (B) described in this paragraph for each period is referred to as the excess income amount.

The portion of
the Incentive Fee based on income for each period will equal 50% of the periods excess income amount, until the cumulative Incentive Fee payments for the period equal 20% of the periods income amount distributed or distributable to
stockholders as described in clause (A) of the preceding paragraph. Thereafter, the portion of the Incentive Fee based on income for the period will equal 20% of the periods remaining excess income amount.

For the years ended December 31, 2012, 2011 and 2010, the Advisor earned $16,997,054, $11,878,159 and $15,108,049, respectively, in
Incentive Fees based on income from the Company.

Annual Incentive Fee Based on Capital Gains. The portion of
the Incentive Fee based on capital gains is calculated and paid on an annual basis beginning on July 1, 2007, the first day of the calendar quarter in which the Public Market Event occurred and each annual period thereafter, ending on
June 30 of the next calendar year. For each annual period, the Company pays the Advisor an Incentive Fee based on the amount by which (A) net realized capital gains, if any, to the extent they exceed gross unrealized capital depreciation,
if any, occurring during the period exceeds (B) the amount, if any, by which the periods hurdle rate exceeds the amount of income used in the determination of the Incentive Fee based on income for the period. The amount of the excess of
(A) over (B) described in this paragraph is referred to as the excess gain amount.

The portion of the Incentive Fee
based on capital gains for each period will equal 50% of the periods excess gain amount, until such payments equal 20% of the periods capital gain amount distributed or distributable to stockholders. Thereafter, the portion of the
Incentive Fee based on capital gains for the period equals an amount such that the portion of the Incentive Fee payments to the Advisor based on capital gains for the period equals 20% of the periods remaining excess gain amount. The result of
this formula is that, if the portion of the Incentive Fee based on income for the period exceeds the periods hurdle, then the portion of the Incentive Fee based on capital gains will be capped at 20% of the capital gain amount.

In calculating whether the portion of the Incentive Fee based on capital gains is payable with respect to any period, the Company
accounts for its assets on a security-by-security basis. In addition, the Company uses the period-to-period method pursuant to which the portion of the Incentive Fee based on capital gains for any period is based on realized capital
gains for the period reduced by realized capital losses and gross unrealized



F-29

##### Table of Contents

capital depreciation for the period. Based on current interpretations of Section 205(b)(3) of the Investment Advisers Act of 1940 by the SEC and its staff, the calculation of unrealized
depreciation for each portfolio security over a period is based on the fair value of the security at the end of the period compared to the fair value at the beginning of the period. Incentive Fees earned in any of the periods described above are not
subject to modification or repayment based upon performance in a subsequent period.

We are required under GAAP to accrue a
hypothetical capital gains Incentive Fee based upon net realized capital gains and unrealized capital appreciation and depreciation on investments held at the end of each period. The accrual of this hypothetical capital gains incentive fee assumes
all unrealized capital appreciation and depreciation is realized in order to reflect a hypothetical capital gains incentive fee that would be payable at each measurement date. If such amount is positive at the end of the period, then we record a
capital gains incentive fee equal to 20% of such amount, less the amount of capital gains related incentive fees already accrued in prior periods. If the resulting amount is negative, the accrual for GAAP in a given period may result in an
additional expense. There can be no assurance that such unrealized capital appreciation will be realized in the future. However, it should be noted that a fee so calculated and accrued would not be payable under the Investment Advisers Act of 1940
or the Management Agreement. Amounts actually paid will be consistent with the Advisers Act which specifically excludes consideration of unrealized capital appreciation.

The capital gains fee due the Advisor as calculated under the Management Agreement as described above, for the years ended December 31, 2012, 2011 and 2010 were zero. In accordance with GAAP the
hypothetical incentive fee for the year ended December 31, 2012, resulted in a capital gains incentive fee of $5,494,735. The hypothetical incentive fee based on capital gains was zero for the year ended December 31, 2011 and 2010.

Advisor Reimbursements

The Management Agreement provides that the Company will reimburse the Advisor for costs and expenses incurred by the Advisor for office space rental, office equipment and utilities allocable to the
Advisor under the Management Agreement, as well as any costs and expenses incurred by the Advisor relating to any non-investment advisory, administrative or operating services provided by the Advisor to the Company. For the years ended
December 31, 2012, 2011 and 2010, the Company incurred $1,991,416, $1,779,734 and $1,622,957, respectively, for such investment advisor expenses under the Management Agreement.

Advisor Stock Transactions

In 2007, the Companys Board of Directors authorized the purchase by the Advisor from time to time in the open market of an
indeterminate number of shares of the Companys common stock, in the Advisors discretion, subject to compliance with the Companys and the Advisors applicable policies and requirements of law. There were no such purchases
during the years ended December 31, 2012, 2011 and 2010.

In March 2011, the Companys Board of Directors authorized the
purchase in a private placement of up to 1,000,000 shares of the Companys common stock, by the Advisor in its discretion, subject to compliance with the Companys and the Advisors applicable policies and requirements of law.
Pursuant to this authorization, on March 16, 2011, the Company issued and sold to the Advisor in a private placement 200,000 shares of common stock for $2,000,000 or $10.00 per share, which was the closing price of the Companys common stock
price on The NASDAQ Global Selecte Market on that date. There were no private placement purchases for the year ended December 31, 2012.

At December 31, 2012 and December 31, 2011, the Advisor owned and had the right to vote approximately 94,000 and 259,000 shares, respectively, of the Companys common stock, representing
less than 1.0% of the total shares outstanding. On such dates, under compensation arrangements for its officers and employees the Advisor owned of record but did not have the right to vote an additional 261,000 and 275,000 shares, respectively, of
the Companys common stock. At December 31, 2012 and 2011, other entities affiliated with the Administrator beneficially owned approximately 6,019,000 and 6,019,000 shares, respectively, of the Companys common stock, representing
approximately 8.2% and 8.2% of the total shares outstanding. An entity affiliated with the Administrator has ownership and financial interests in the Advisor.

4. Earnings per share

The following information sets forth the computation
of basic and diluted net increase in net assets per share (earnings per share) resulting from operations for the years ended December 31, 2012, 2011 and 2010.



|                                                                             |  |                            |            |  |                            |   |            |                            |  |   |            |

|Numerator for basic and diluted net increase in net assets per share         |  | $                          | 57,351,233 |  |                            | $ | 76,920,509 |                            |  | $ | 71,549,561 | 
|Denominator for basic and diluted net increase in net assets per share       |  |                            | 73,623,983 |  |                            |   | 73,037,357 |                            |  |   | 62,663,002 | 
|Basic/diluted net increase in net assets per share resulting from operations |  | $                          | 0.78       |  |                            | $ | 1.05       |                            |  | $ | 1.14       | 

Diluted net increase in net assets per share from operations equals basic net increase in net assets per
share from operations for each period because there were no common stock equivalents outstanding during the above years.

5. Investments

Purchases of investments for the years ended December 31, 2012, 2011 and 2010 totaled $317,097,868, $401,530,203 and

Market and Credit Risk

In the normal course of business, the Company invests in securities and enters into transactions where risks exist due to fluctuations in the market (market risk) or failure of the issuer of a security to
meet all its obligations (issuer credit risk). The value of securities held by the Company may decline in response to certain events, including those directly involving the issuers whose securities are owned by the Company; conditions affecting the
general economy; overall market changes; local, regional or global political, social or economic instability; and currency and interest rate and price fluctuations. Similar to issuer credit risk, the Company may be exposed to counterparty credit
risk, or the risk that an entity with which the Company has unsettled or open transactions may fail to or be unable to perform on its commitments. The Company manages counterparty risk by entering into transactions only with counterparties that they
believe have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties. Financial assets, which potentially expose the Company to market, issuer and counterparty credit risks, consist
principally of investments in portfolio companies. The extent of the Companys exposure to market, issuer and counterparty credit risks with respect to these financial assets is generally approximated by their value recorded in the consolidated
statements of assets and liabilities. The Company is also exposed to credit risk related to maintaining all of its cash at a major financial institution.

The Company has investments in lower rated and comparable quality unrated senior and junior secured, unsecured and subordinated debt securities and loans, which are subject to a greater degree of credit
risk than more highly rated investments. The risk of loss due to default by the issuer is significantly greater for holders of such securities and loans, particularly in cases where the investment is unsecured or subordinated to other creditors of
the issuer.

6. Derivatives

Foreign Currency

The Company may enter into forward foreign
currency contracts from time to time to facilitate settlement of purchases and sales of investments denominated in foreign currencies or to help mitigate the impact that an adverse change in foreign exchange rates would have on the value of the
Companys investments denominated in foreign currencies. A forward foreign currency contract is a commitment to purchase or sell a foreign currency at a future date (usually the security transaction settlement date) at a negotiated forward
rate. These contracts are marked-to-market by recognizing the difference between the contract exchange rate and the current market rate as unrealized appreciation or depreciation. Realized gains or losses are recognized when contracts are settled.
The Companys forward foreign currency contracts generally have terms of approximately three months. The volume of open contracts at the end of each reporting period is reflective of the typical volume of transactions during each calendar

Warrants

The Company holds warrants and options in certain portfolio companies in an effort to achieve additional investment return. In purchasing
warrants and options, the Company bears the risk of an unfavorable change in the value of the underlying equity interest. The aggregate fair value of warrants and options as of December 31, 2012 and December 31, 2011 represents 2.4% and
0.9%, respectively, of the Companys net assets.

7. Debt

Under the terms of the Companys amended and restated Senior Secured, Multi-Currency Credit Agreement (the Credit Facility), as amended on April 20, 2010, certain lenders agreed to
extend credit to the Company in an aggregate principal amount not to exceed $375,000,000 outstanding, at any one time, consisting of $275,000,000 of revolving loan commitments and $100,000,000 of term loan commitments. The Credit Facility is secured
by substantially all of the assets in the Companys portfolio, including cash and cash equivalents. Subject to certain exceptions, pricing for outstanding borrowings is at LIBOR plus an applicable spread of either 3.00% or 3.25% for revolving
loans, based on a pricing grid using the Companys credit rating, and LIBOR plus 3.00% for term loans. The Credit Facility does not contain a LIBOR floor requirement. At December 31, 2012, the effective LIBOR spread under the Credit
Facility was 3.10%. Term loan commitments under the Credit Facility have been fully drawn and, once repaid, may not be reborrowed. The Credit Facility also includes an accordion feature that allows the Company, under certain
circumstances, to increase the size of the Credit Facility by up to an additional $275,000,000 of revolving loan commitments and $250,000,000 of term loan commitments. The Credit Facility is used to supplement the Companys equity capital to
make additional portfolio investments and for other general corporate purposes.

At December 31, 2012, the Company had
$171,850,000 drawn on the Credit Facility versus $168,000,000 at December 31, 2011. Subject to compliance with applicable covenants and borrowing base limitations, the remaining amount available under the Credit Facility was $203,150,000 at
December 31, 2012 and $207,000,000 at December 31, 2011.

In January 2011, the Company closed a private placement
issuance of $158,000,000 in aggregate principal amount of five-year, senior secured notes with a fixed interest rate of 6.50% and a maturity date of January 18, 2016 and $17,000,000 million in aggregate principal amount of seven-year, senior
secured notes with a fixed interest rate of 6.60% and a maturity date of January 18, 2018 (collectively, the Senior Secured Notes). The Senior Secured Notes were sold to certain institutional accredited investors pursuant to an
exemption from registration under the Securities Act of 1933, as amended. Interest on the Senior Secured Notes is due semi-annually on January 18 and July 18, commencing on July 18, 2011.

The average debt outstanding during the years ended December 31, 2012, 2011 and 2010 was $381,451,093, $291,353,425 and
$205,151,507, respectively. The maximum amounts borrowed during the years ended December 31, 2012, 2011 and 2010 were $469,900,000, $402,000,000 and $314,000,000, respectively.

The weighted average annual interest cost for the years ended December 31, 2012, 2011 and 2010 was 4.90%, 5.23% and 2.41%,
respectively, exclusive of commitment fees and of other prepaid expenses related to establishing the Credit Facility and the Senior Secured Notes. With respect to any unused portion of the commitments under the Credit Facility and the Senior Secured
Notes, the Company incurs an annual commitment fee of 0.50%. Commitment fees incurred for the years ended December 31, 2012, 2011 and 2010 were $862,540, $1,261,681 and $1,223,193, respectively.

At December 31, 2012, the Company was in compliance with all covenants required under the Credit Facility and the Senior Secured
Notes.

In 2008, the Companys Board of Directors approved a share repurchase plan under which the Company
may repurchase up to 2.5 percent of its outstanding shares of common stock from time to time in open market or privately negotiated transactions. In 2009, the Board of Directors approved an extension and increase to the plan which authorized the
Company to repurchase up to an additional 2.5 percent of its outstanding shares of common stock. In May 2012, the repurchase plan was further extended through the earlier of June 30, 2013 or until the approved number of shares has been
repurchased. During the year ended December 31, 2012, the Company purchased zero shares of its common stock on the open market. During the year ended December 31, 2011, the Company purchased a total of 463,828 shares of its common stock on
the open market for $4,050,776, including brokerage commissions. Since inception of the repurchase plan through December 31, 2012, the Company has purchased 1,425,507 shares of its common stock on the open market for $9,476,676, including
brokerage commissions. At December 31, 2012, the total number of remaining shares authorized for repurchase was 1,331,143. The Company currently holds the shares it repurchased in treasury.

For the years ended December 31, 2012, 2011 and 2010, dividends and distributions paid to common stockholders were $76,572,302,
$80,361,895 and $80,455,656, respectively. For the years ended December 31, 2012, 2011 and 2010, dividends and distributions reinvested pursuant to the Companys dividend reinvestment plan were $5,591,912, $8,021,087 and $5,468,133,
respectively.

In June 2010, the Companys stockholders approved an amendment to the Companys Certificate of
Incorporation to increase the number of authorized shares of the Companys common stock from 100,000,000 to 200,000,000. The amendment was effective on that date.

9. Guarantees and contingencies

In the normal course of business, the
Company may enter into guarantees on behalf of portfolio companies. Under these arrangements, the Company would be required to make payments to third parties if the portfolio companies were to default on their related payment obligations. The
Company has no such guarantees outstanding at December 31, 2012 and December 31, 2011.

In the normal course of business,
the Company enters into contractual agreements that provide general indemnifications against losses, costs, claims and liabilities arising from the performance of individual obligations under such agreements. The Company has had no prior claims or
payments pursuant to such agreements. The Companys individual maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Company that have not yet occurred. However, based on
managements experience, the Company expects the risk of loss to be remote.

From time to time, the Company may be a
party to certain legal proceedings incidental to the normal course of its business, including the enforcement of the Companys rights under contracts with its portfolio companies.

While the Company cannot predict the outcome of these legal proceedings with certainty, it does not expect that these proceedings will have a material effect on its consolidated financial
statements.

10. Fair value of financial instruments

Fair Value Measurements and Disclosure

ASC 820-10 defines fair
value, establishes a framework for measuring fair value and requires disclosures about fair value measurements. ASC 820-10 defines fair value as the price that the Company would receive upon selling an investment or pay to transfer a liability in an
orderly transaction to a market participant in the principal or most advantageous market for the investment. ASC 820-10 emphasizes that valuation techniques maximize the use of observable market inputs and minimize the use of unobservable inputs.
Inputs refer broadly to the assumptions that market participants would use in pricing an asset or liability, including assumptions about risk. Inputs may be observable or unobservable. Observable inputs are inputs that reflect the assumptions market
participants would use in pricing an asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Companys assumptions about the assumptions market
participants would use in pricing an asset or liability developed based on the best information available in the circumstances.

Level 1  Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access.

Level 2  Valuations based on unadjusted quoted prices in markets that are not active or for which all significant
inputs are observable, either directly or indirectly.

Level 3  Valuations based on inputs that are
unobservable and significant to the overall fair value measurement. The inputs into the determination of fair value may require significant management judgment or estimation.

Transfers between levels, if any, represent the value as of the beginning of the period of any investment where a change in the pricing level occurred from the beginning to the end of the period.

The Companys valuation policy and fair value disclosures are consistent with ASC 820-10. The Company evaluates the
source of inputs, including any markets in which its investments are trading, in determining fair value and categorizes each investment within the fair value hierarchy pursuant to ASC 820-10.

Under the 1940 Act, the Company is required to separately identify non-controlled investments where it owns 5% or more of a portfolio
companys outstanding voting securities as investments in affiliated companies. In addition, under the 1940 Act, the Company is required to separately identify investments where it owns more than 25% of a portfolio companys
outstanding voting securities as investments in controlled companies. Detailed information with respect to the Companys non-controlled non-affiliated, non-controlled affiliated and controlled investments is contained in the
accompanying consolidated schedules of investments and other consolidated financial statements. The information in the tables below is presented on an aggregate portfolio basis, without segregating the non-controlled non-affiliated, non-controlled
affiliated and controlled investment categories.

The carrying values of the Companys financial instruments approximate
fair value. The carrying values of receivables, other assets, accounts payable and accrued expenses approximate fair value due to their short maturities. The fair value of the Companys Credit Facility and Senior Secured Notes is derived by
taking the average of the high and low quotes as obtained from a broker. The fair value of the Credit Facility and Senior Secured Notes would be classified as Level 2 with respect to the fair value hierarchy.

The carrying and fair values of the Companys Credit Facility payable were $171,850,000 and $168,413,000 at December 31, 2012
and $168,000,000 and $157,080,000 at December 31, 2011, respectively. The carrying and

fair values of the Companys Secured Senior Notes were $175,000,000 and $189,507,410 at December 31, 2012, respectively and $175,000,000 and $180,815,000 at December 31, 2011. The
carrying and fair values of the Companys total debt outstanding were therefore $346,850,000 and $357,920,410 at December 31, 2012, respectively and $343,000,000 and $337,895,000 at December 31, 2011.

The following tables summarize the fair values of the Companys investments, forward foreign currency contracts and cash and cash
equivalents based on the inputs used at December 31, 2012 and December 31, 2011 in determining such fair values:

The significant unobservable inputs used in the market approach of fair value measurement of
the Companys investments are the market multiples of earnings before income tax, depreciation and amortization (EBITDA) of the comparable guideline public companies. The independent valuation firms select a population of public
companies for each investment with similar operations and attributes of the subject company. Using these guideline public companies data, a range of multiples of enterprise value to EBITDA is calculated. The independent valuation firms select
percentages from the range of multiples for purposes of determining the subject companys estimated enterprise value based on said multiple and generally the latest twelve months EBITDA of the subject company (or other meaningful measure).
Significant increases or decreases in the multiple will result in an increase or decrease in enterprise value, resulting in an increase or decrease in the fair value estimate of the investment.

The significant unobservable input used in the income approach of fair value measurement of the Companys investments is the
discount rate or market yield used to discount the estimated future cash flows expected to be received from the underlying investment, which include both future principal and interest payments. Significant increases or decreases in the discount rate
would result in an decrease or increase in the fair value measurement. Included in the consideration and selection of discount rates are the following factors: risk of default, rating of the investment and comparable company investments, and call
provisions.

The ranges of significant unobservable inputs used in the fair value measurement of the Companys Level 3
investments as of December 31, 2012 were as follows:

12. Federal tax information

Dividends from net investment income and distributions from net realized capital gains are determined in accordance with U.S. federal income tax regulations, which may differ from those amounts determined
in accordance with GAAP. These book/tax differences are either temporary or permanent in nature. To the extent these differences are permanent, they are charged or credited to paid-in-capital, distributions in excess of net investment income or
accumulated net realized gain (loss), as appropriate, in the period that the differences arise. The following temporary and permanent differences at December 31, 2012 and 2011 primarily attributable to differences in the tax treatment of
certain debt securities, the tax characterization of income from partnership investments, foreign currency transactions, non-deductible expenses and differences in accounting for certain upfront fees (treated as taxable income when received and may
be accreted over the life of the respective investment for financial reporting purposes), were reclassified for tax purposes as follows:

Taxable income generally differs from the change in net assets resulting from operations for financial
reporting purposes due to temporary and permanent differences in the recognition of income and expenses, and generally excludes net unrealized appreciation or depreciation, as unrealized gains or losses are not included in taxable income until they
are realized.

Book and tax basis differences relating to stockholder dividends and distributions and other permanent book and
tax differences are reclassified among the Companys capital accounts. In addition, the character of income and gains to be distributed is determined in accordance with income tax regulations that may differ from GAAP.

For the tax year ended December 31, 2012, the Company had a net capital loss carry forward of
$179,831,735, which can be used to offset future capital gains. If not utilized against future gains, $9,065,897 expires in 2017 and $95,856,015 expires in 2018. The remaining $74,909,823 of this capital loss carry forward will not be subject to
expiration and must be utilized prior to the losses subject to expiration.

As a RIC, the Company is subject to a
non-deductible federal excise tax of 4% if it does not distribute at least 98% of its ordinary income, excluding net short-term capital gains, in any calendar year; 98.2% of its capital gains in excess of capital losses for each one-year period
ended October 31; and any ordinary income and net capital gains for preceding years that were not distributed during such years. For each of the years ended December 31, 2012 and 2011, no provision for federal excise tax was recorded.

For income tax purposes, distributions paid to stockholders are reported as ordinary income, non-taxable (return of capital),
capital gains, or a combination thereof. The tax character of distributions paid or declared during the year ended December 31, 2012 was $5,434,267 of ordinary income and $71,138,035 of return of capital. For the tax year ended
December 31, 2011, the tax character of distributions paid or declared was $59,230,030 of ordinary income and $21,131,865 of return of capital.

ASC 740-10, Income Taxes (ASC 740-10) clarifies the accounting for income taxes by prescribing the minimum recognition threshold an uncertain tax position is required to meet before tax
benefits associated with such uncertain tax position are recognized in the consolidated financial statements. Based on its analysis of its tax position, the Company has concluded that it does not have any uncertain tax positions that met the
recognition or measurement criteria of ASC 740-10.

The Company files U.S. federal and various state and local tax returns. No
income tax returns are currently under examination. The statute of limitations on the Companys U.S. federal income tax returns remains open for each of the four years ended December 31, 2012. The statute of limitations on the
Companys state and local tax returns may remain open for an additional year depending upon the jurisdiction.

14. Subsequent events

The Company has reviewed subsequent events occurring through the date that these consolidated financial statements were issued, and determined that no subsequent events occurred requiring accrual or
disclosure, except as disclosed below and elsewhere in these Notes to Consolidated Financial Statements.

On February 19, 2013
the Company closed a private offering of $100,000,000 in aggregate principal amount of 5.50% unsecured convertible senior notes due 2018. The initial purchasers of the Notes fully exercised their overallotment option and purchased an additional
$15,000,000 in aggregate principal amount of the Notes. The closing of the overallotment option took place on March 4, 2013. With the exercise of the overallotment option, a total of $115,000,000 in aggregate principal amount of the Notes have been
sold. Net proceeds to the Company from the offering, including the exercise of the overallotment option, are approximately $111,300,000. The Notes were only offered to qualified institutional buyers as defined in the Securities Act of 1933, as
amended (the Securities Act) pursuant to Rule 144A under the Securities Act.

The Notes are unsecured and bear
interest at a rate of 5.50% per year, payable semi-annually in arrears. In certain circumstances and during certain periods, the Notes are convertible into cash, shares of BlackRock Kelso Capitals common stock or a combination of cash and
shares of the Companys common stock, at the Companys election, at an initial conversion rate of 86.0585 shares of common stock per $1,000 principal amount of the Notes, which is equivalent to an initial conversion price of approximately
$11.62 per share of the Companys common stock, subject to defined anti-dilution adjustments. The Company does not have the right to redeem the Notes prior to maturity. The Notes mature on February 15, 2018, unless repurchased or converted
in accordance with their terms prior to such date.

On March 6, 2013, the Companys Board of Directors declared a
dividend of $0.26 per share, payable on April 2, 2013 to stockholders of record at the close of business on March 19, 2013.

In March 2013, the Company received binding commitments from several lenders for a $350 million senior secured multi-currency credit facility, subject to definitive documentation and closing, with a
maturity date of March 2017.
